Check Device Compatibility First

Activate Your eSIM in Minutes A Simple Step by Step Guide

Ready to free yourself from fiddling with tiny plastic SIM cards? Activating an eSIM is a simple process where you scan a QR code from your carrier or download a profile directly to your phone’s settings. Once installed, you can immediately manage multiple plans digitally and switch between them without ever swapping a physical card.

Check Device Compatibility First

Before attempting to activate an eSIM, you must check device compatibility first by ensuring your specific smartphone model supports eSIM technology and is not carrier-locked to an incompatible network. Most modern devices list eSIM support in Settings under “About Phone” or “Cellular.” A common question is: Q: How can I quickly confirm my device is ready for eSIM activation? A: Look for “Add eSIM” or “Add Cellular Plan” in your mobile network settings; if visible, compatibility is likely confirmed. Without this preliminary check, activation will fail, wasting time and potentially requiring a new physical SIM. Always verify compatibility directly with your carrier’s official support page for your exact device model before initiating any eSIM activation process.

Confirm your smartphone model supports eSIM technology

Before starting activation, verify your eSIM device compatibility by checking your phone’s settings menu for “Add eSIM” or “Mobile Plans.” Most modern flagships from Apple, Samsung, and Google support it, but older or carrier-locked models may not. Double-check that your specific model variant, not just the brand, is listed on the manufacturer’s support page. Does my smartphone need a specific software version for eSIM? Yes—ensure your phone runs the latest OS update, as older firmware can block eSIM detection even on compatible hardware.

Verify carrier and network provider eSIM readiness

Before attempting activation, confirm carrier and network provider eSIM readiness by checking your current operator’s support page or app. Not all providers offer eSIM for every plan, so verify your specific account enables eSIM provisioning. For a new network, enter your device’s IMEI on their compatibility checker to ensure their eSIM profile will function properly. Even if your device is unlocked, the carrier must actively support eSIM transfer for your line. Skipping this step may cause activation failure or require physical SIM reversion.

Verify carrier and network provider eSIM readiness by checking plan eligibility, device IMEI against the provider’s database, and ensuring the account allows eSIM provisioning before beginning activation.

Ensure the device is unlocked and not carrier-restricted

Before activating an eSIM, verify the device is unlocked and not carrier-restricted. A locked phone will reject a competing carrier’s eSIM profile, causing activation failure. Check your device’s settings under “Cellular” or “Network” for a “No SIM restrictions” message. For iPhones, navigate to Settings > General > About and look for “Carrier Lock” set to “No SIM restrictions.”

• Contact your original carrier to request an unlock if your device is locked.
• Confirm the unlock is permanent—temporary unlocks may block future eSIM downloads.
• Use the IMEI check on a carrier’s website to verify unlock status before purchasing an eSIM plan.
• Carrier restriction applies to both contract and prepaid devices; ensure no financial obligations remain.

Select a Mobile Plan Provider

To activate an eSIM, your first task is selecting a provider that explicitly supports eSIM activation for your specific device model. Check their website for a dedicated “eSIM” section since not all plans offer it. How do I know if my provider is eSIM-ready? Look for an option to “Get a QR code” or “Download an eSIM profile” during checkout—if they only offer a physical SIM, move on. Once chosen, during activation you’ll either scan a QR code from your confirmation email or enter a manual activation code in your phone’s cellular settings. Confirm your provider permits eSIM transfers between devices, as some lock it to one handset. Prioritize providers with a straightforward, app-based setup flow to avoid lengthy customer support calls when your eSIM doesn’t provision immediately.

Choose between your current carrier or a global eSIM service

When selecting a provider for activation, your core decision is between your current carrier or a global eSIM service. Sticking with your current carrier offers seamless integration with your existing number and billing, often allowing instant activation through their app. Conversely, a global eSIM service provides immediate access to affordable local data plans in multiple countries without contract commitments. This choice hinges on your travel frequency: for occasional trips, a global data-only eSIM is simpler and cheaper, while maintaining your primary number abroad requires your current carrier’s roaming plan.

Compare prepaid, postpaid, and travel eSIM options

When selecting a provider, comparing prepaid, postpaid, and travel eSIM options directly impacts activation. Prepaid eSIMs require upfront payment and immediate activation via a QR code or app, offering fixed data without a contract. Postpaid eSIMs are activated after credit approval and linking to your existing account, typically through the carrier’s portal. Travel eSIMs are prepaid, specialized plans activated before departure by scanning a QR code, often with a set validity window. To decide:

1. Assess your usage duration—prepaid for short-term, postpaid for ongoing local need, travel eSIM for trips.
2. Verify provider compatibility with your device model.
3. Choose a plan based on which activation method (instant scan vs. account setup) suits your timing.

Purchase a plan directly from the provider’s website or app

To purchase an eSIM plan directly, open your chosen provider’s official website or app. First, navigate to the eSIM section. Second, select a data plan matching your usage and duration. Third, create an account if required. Fourth, complete payment; most accept credit cards or digital wallets. Fifth, you will receive a QR code or activation code instantly via email or in-app. Save this to your device, as it is required to download and activate the eSIM profile. This method ensures you get the plan without third-party markup.

Receive Your eSIM Activation Details

To activate your eSIM, receiving the activation details is the first critical step. After purchase, your carrier will deliver a QR code or a manual activation code—check your email inbox and spam folder immediately. Open this message on the device you intend to activate to avoid switching screens later. Do not delete or share these credentials until the eSIM is confirmed active. A nuanced reality: Some carriers embed the activation code in the email body, while others attach a PDF, so inspect every attachment thoroughly. Tap on the QR code to trigger your device’s cellular plan setup, or enter the code manually if scanned visually fails. This information is your digital key—handle it with precision to unlock immediate connectivity.

Obtain the QR code via email or account dashboard

To begin your eSIM activation, obtain the QR code via email or account dashboard immediately after purchase. Your provider sends a unique QR code directly to your registered email, often within minutes. Alternatively, log into your account dashboard to instantly access and download the QR code. This code is essential for scanning during setup.

• Check your email inbox and spam folder for the QR code attachment.
• Access your account dashboard under “My eSIM” or “Orders” to retrieve it.
• Save the QR code screenshot or print it for offline scanning.

Look for an activation code or manual entry details

Once your eSIM purchase completes, your provider sends the activation details. Locate your unique QR code or manual entry details in the account dashboard, email confirmation, or provider app. No QR code? The activation code often appears as a numeric SM-DP+ address and confirmation code. Follow this sequence for manual input:

1. Open your device’s cellular settings and select “Add eSIM” or “Add Data Plan.”
2. Choose “Enter Details Manually” instead of scanning a QR.
3. Copy the SM-DP+ address (a long URL) and the activation code exactly as shown.

Double-check every character—mistakes block activation. Save a screenshot of these details as a backup before proceeding.

Keep your confirmation number and plan summary handy

Once you complete your eSIM purchase, keep your confirmation number and plan summary handy before starting activation. This number links your order to the carrier’s system, enabling faster troubleshooting if the eSIM fails to download. To organize these details:

1. Save the email containing your confirmation number and plan summary in a dedicated “eSIM Activation” folder.
2. Take a screenshot of the summary showing your plan’s data cap, expiry date, and QR code (if applicable).
3. Store the screenshot in a secure, easily accessible location—like a device notes app—so you can reference it during setup or when contacting support.

Add an eSIM on iPhone

To add an eSIM on your iPhone for activation, open **Settings** > **Cellular** > **Add Cellular Plan**. Your carrier will provide a QR code or an activation code; scan it using your iPhone’s camera, or tap the carrier’s app if available. After scanning, label your new plan (e.g., “Travel” or “Business”) and choose your default line for calls and data. A key step: ensure your iPhone is connected to Wi-Fi during setup to download the eSIM profile. Q: Do I need to remove my physical SIM to add an eSIM? A: No, iPhone supports Dual SIM with both a physical SIM and eSIM active simultaneously. Confirm activation by checking the “Cellular Plans” list—your eSIM should show “Turn On This Line” active, ready for use.

Navigate to Settings and tap Cellular or Mobile Data

Begin by opening the Settings app on your iPhone. Scroll down and tap “Cellular” (or “Mobile Data” in some regions). This menu manages all network connections, including eSIM lines. You will see a list of your current plans; if no eSIM is added, tap “Add Cellular Plan.” Your iPhone will then scan for a QR code or prompt you to enter details manually. If your carrier sent a confirmation code, enter it here. Ensure your device is connected to Wi-Fi during this process, as the activation requires a stable internet connection.

1. Open Settings
2. Tap Cellular or Mobile Data
3. Select Add Cellular Plan
4. Follow on-screen prompts to scan QR or input carrier info

Select Add Cellular Plan and scan the provided QR code

To activate an eSIM, navigate to **Settings > Cellular > Add Cellular Plan** on your iPhone, then scan the provided QR code from your carrier. Ensure your camera is clean, hold it steady over the code, and wait for the automatic detection. A prompt will appear to confirm plan addition; tap “Continue” to finalize. Position the QR code in optimal lighting to avoid scanning errors, especially with reflective surfaces.

• Use the iPhone’s native camera scanner within the Add Cellular Plan menu; no third-party app is required.
• If the QR code fails, manually enter the activation details under China eSIM “Enter Details Manually” as a backup.
• Post-scan, the eSIM label (e.g., “Business Line”) can be customized in Cellular settings.
• Ensure the QR code is from your carrier’s official eSIM delivery, as generic codes may not activate.

Label your plans like Primary, Secondary, or Travel for clarity

To prevent confusion with multiple eSIMs, you must label your plans immediately after activation. Use clear eSIM labels like “Primary” for your local number and “Secondary” or “Travel” for a temporary data plan. This simple step ensures your iPhone defaults correctly for calls, messages, and data. Follow this sequence:

1. Go to **Settings > Cellular** and tap the new eSIM.
2. Select **Cellular Plan Label**.
3. Choose a preset like “Primary” or “Travel,” or tap **Custom Label** to type your own name.

Assigning distinct labels now eliminates guesswork later, letting you switch between plans and manage your line for travel moments without errors.

Set Up eSIM on Android Devices

To Set Up eSIM on Android Devices for activation, begin by opening **Settings**, then tap “Connections” or “Network & Internet.” Select “SIM card manager” or “Mobile network,” then choose “Add eSIM.” Your device will prompt you to scan the QR code provided by your carrier. Alternatively, you may enter the activation details manually via the SM-DP+ address and confirmation code. Once scanned, follow on-screen instructions to complete the download and assign the eSIM profile. Ensure your device is connected to Wi-Fi during this process. After activation, you can label the eSIM line for clarity and set your preferred SIM for data and calls.

Open Settings and go to Network & Internet or Connections

Begin by unlocking your Android device and locating the Settings app, typically represented by a gear icon. Once opened, you must navigate to the network controls. On stock Android, this is labeled Network & Internet; on Samsung and other brands, it may appear as Connections. This section is the central hub for all wireless communications. Tapping either option will reveal the menu for managing your SIMs. Do not proceed to any other settings section, as this is the only path to initiate the eSIM activation process. Your next step, adding a mobile plan, will only appear here.

Why do I need to go to “Network & Internet” or “Connections”?
This section houses the eSIM setup options. You cannot activate a digital SIM from general device settings like “About Phone” or “Display.” The carrier’s eSIM profile must be installed specifically through the SIM manager located within Network & Internet or Connections.

Tap Add Mobile Plan or SIM Manager and scan the QR code

Once your device is unlocked, tap Add Mobile Plan or SIM Manager from the Settings menu, typically under Network & Internet. Select “Add Carrier” or the plus icon, then authorize the camera to scan the carrier-provided QR code. Align the code within the viewfinder until the device confirms the activation profile; the eSIM will install automatically. This direct scan eliminates manual entry errors and delays, making provisioning instantly reliable. After a successful scan, wait for the “Downloading eSIM” prompt, then restart your phone to finalize connectivity.

Manually enter the activation code if the QR scan fails

If your phone’s camera won’t scan the QR code—maybe due to glare, a damaged code, or poor lighting—you can instead manually enter the activation code. This code is usually a long string of numbers and letters, often labeled as an “SM-DP+ address” plus an “activation code.” On your device, tap “Enter details manually” in the eSIM setup menu, then type both parts exactly as provided by your carrier. Double-check for typos, as errors will prevent activation. Once entered, confirm to download and install the eSIM profile.

If scanning fails, simply copy or type your SM-DP+ and activation code manually to finish setup.

Activate via Carrier App

You’ve just unboxed your new phone and pulled out the QR code from your carrier. Instead of messing with settings, you open the carrier’s own app. Tapping Activate eSIM instantly triggers a scan that pulls your plan details directly from the account you’re already logged into. Within seconds, the eSIM profile installs silently in the background. No need to hunt for a physical card or a Wi-Fi hotspot—the app handles both data and activation in one fluid step. It feels almost anticlimactic, the way the phone just connects without any fuss. The entire process is contained within that one familiar interface, so you never leave the app until it confirms your new line is ready.

Download your carrier’s official app from the app store

To begin eSIM activation, download your carrier’s official app directly from the Apple App Store or Google Play Store. Search specifically for your provider’s name to avoid counterfeit apps. Once installed, open the app and locate the eSIM or cellular plan section—typically found under “Add a New Line” or “Manage Plans.” The app will then guide you through verifying your identity and installing the eSIM profile over Wi-Fi.

• Check app ratings and developer name to confirm authenticity before downloading.
• Ensure your phone is connected to Wi-Fi for a stable, uninterrupted download.
• Have your account login credentials ready to authenticate directly within the carrier’s app.

Log into your account and follow the embedded eSIM setup flow

Once you’re in the carrier app, simply log into your account using your regular credentials. After that, look for the option to start a new line or device setup, which will trigger the embedded eSIM setup flow. Just follow the on-screen prompts—they’ll guide you through scanning a QR code or tapping a confirmation button to install the eSIM profile directly onto your phone. The whole process feels like clicking through a quick app update, and your new eSIM will be ready in just a couple of minutes.

Confirm installation and restart the phone if prompted

After the carrier app finalizes provisioning, you must confirm the installation and restart the phone if prompted. Tapping “Confirm” applies the eSIM profile to your device’s radio firmware; skipping this step leaves the profile unactivated. Some carriers force a mandatory reboot to refresh the baseband. Do not dismiss this prompt, as a restart ensures the phone re-registers with the network under the new eSIM, preventing service gaps. If no restart is requested, your device should auto-activate within minutes.

Configure Default Line and Data Preferences

After activating your eSIM, you must configure the default line and data preferences to manage dual SIM functionality. In your device’s cellular settings, designate the eSIM or physical SIM as the default line for voice, messaging, and contacts. For data, set either SIM as the primary cellular data line, or enable “Allow Cellular Data Switching” to automatically use the other SIM when the primary has poor coverage. This setting is often overlooked, but it prevents unexpected charges by ensuring calls or messages route through the intended line. Both choices directly impact how your activated eSIM handles connectivity.

Designate a default voice line for calls and texts

After activating your eSIM, you must set a default voice line to control which number handles outgoing calls and sends text messages. In your device’s Cellular settings, find the option to designate a default voice line for calls and texts. Choose your eSIM as the primary line to ensure all dial-outs and SMS use its number. This prevents accidental billing from a secondary physical SIM and streamlines your communication. Confirm the selection and test by calling a contact. This single assignment locks in your preference, making every interaction intentional and error-free.

Choose which SIM handles mobile data by default

After activating your eSIM, you must choose which SIM handles mobile data by default to control your internet connection. This setting prevents data overage on a limited plan. To configure it, navigate to your device’s mobile network or SIM card manager. You will see your physical SIM and eSIM listed. Tap the data preference option, then select your eSIM for primary data or your physical SIM as a fallback. The

1. Open Settings > Connections or Mobile Network
2. Select SIM Manager
3. Tap “Mobile data” or “Default data SIM”
4. Choose the eSIM or physical SIM

This ensures your data always routes through your chosen line.

Set up call forwarding or dual-SIM management as needed

Once your eSIM is active, head into **Set up call forwarding or dual-SIM management as needed** to control how calls are handled. You can forward calls from your physical SIM to the eSIM (or vice versa) so you never miss a contact. For dual-SIM setups, assign one line for work calls and the other for personal data, or set a default for outgoing calls. Configure these forwarding rules in your phone’s SIM settings—typically under “Call Forwarding” or “Dual SIM Settings.” Test your setup by placing a test call to ensure the routing works as expected.

Q: Can I forward calls from my eSIM to my physical SIM?
A: Yes—most phones let you set up call forwarding between any active SIM, so choose the source line and enter your physical SIM’s number to redirect calls.

Troubleshoot Common Activation Issues

If your eSIM activation fails, first ensure your device is unlocked and connected to Wi-Fi. A common issue is a corrupted or expired QR code; contact your carrier for a fresh one. Q: What if activation says “No Service”? A: Restart your phone, toggle Airplane Mode, and verify the eSIM profile is correctly installed under Settings > Cellular. Check that your device’s software is up to date, as outdated versions often block eSIM provisioning. If the QR code scan shows an error, manually enter the activation details (SM-DP+ address and confirmation code) provided by your carrier. Deleting any previous failed profiles before retrying also resolves conflicts.

Reboot the device if the eSIM fails to appear in settings

If the eSIM profile does not appear in your device’s cellular settings after scanning the QR code or entering the activation code, a simple device reboot can resolve the issue. This action forces the operating system to reload its baseband firmware and reinitialize the eSIM slot. A stuck or pending system process that blocked the profile’s recognition is often cleared by this restart. First, fully power off the device, wait 10 seconds, then turn it back on. Immediately navigate to Settings > Cellular to verify the eSIM now displays as a secondary line. If not, re-scan the QR code before attempting further steps.

Reboot the device if the eSIM fails to appear in settings—restarting forces the system to reload firmware and reinitialize the eSIM slot, often clearing pending processes that block profile recognition.

Check for carrier updates under System or About Phone

To resolve eSIM activation failures, navigate to the device’s **System** or **About Phone** menu and select **Software Update** or **Carrier Settings Update**. An outdated carrier configuration can prevent the phone from recognizing the eSIM profile or connecting to the network. Manually checking for and installing any available carrier updates ensures the device has the latest provisioning data. This step is often necessary after inserting a new eSIM or when activation hangs at “No Service.”

Why is checking for carrier updates under System or About Phone crucial for eSIM activation? It forces the device to download the current network settings needed to authenticate the eSIM, without which the profile may fail to register.

Contact provider support for expired or invalid QR codes

If your eSIM activation QR code displays as expired or invalid, immediately contact provider support for expired or invalid QR codes. Do not attempt to re-scan it repeatedly, as this will not resolve the underlying issue. The provider must issue a fresh QR code from their system. Follow these steps:

1. Locate your account or order number to reference during the call.
2. Access the support channel specified in your activation email (live chat, phone, or ticket system).
3. Inform the agent that the QR code generated an expiration or invalid error, and request a new code be sent to your registered email or directly to your device.

Only a provider can reset the validity window or regenerate a corrupted code; self-service resend options rarely work for expired tokens.

Switch or Transfer an eSIM to a New Phone

Switching or transferring an eSIM to a new phone requires initiating a reactivation through your carrier. You typically download the eSIM activation profile onto your new device via a QR code or carrier app. Critically, you must first delete the eSIM from your old phone, as most carriers allow only one active install per line. After removal, scan the QR code on your new phone or follow the app prompts. The profile will install, and your cellular plan activates instantly. Always keep a screenshot of your eSIM QR code for future transfers; carriers may not resend it without a request. This process takes minutes and restores full service without a physical SIM.

Remove the eSIM from your old device via settings

Before activating your eSIM on a new phone, remove the eSIM from your old device via settings to prevent connectivity conflicts. On iPhone, navigate to Settings > Cellular > select the plan > tap “Remove Cellular Plan.” On Android, go to Settings > Connections > SIM Manager, then tap the eSIM and choose “Delete” or “Remove.” This deactivation frees the eSIM profile for transfer; some carriers require this step before scanning a new QR code. Failing to erase the profile may keep the old device linked to your plan, blocking activation on the new phone. Complete this on your old device while it is connected to Wi-Fi or cellular data.

Request a new QR code or reissue from your carrier

If you lose the original QR code or need to transfer service, you must request a new QR code or reissue from your carrier. Log into your account or contact support, specifying eSIM reissue. The carrier invalidates the old profile and generates a fresh QR code—this ensures security and a clean activation. The code is typically emailed or appears in your account instantly.

What if my carrier can’t reissue the QR code? Most major providers support reissue, but if they don’t, ask for a direct eSIM installation link or a manual activation code (SM‑DP+ address) to enter in your phone’s settings.

Follow the same activation steps on the new device

Once your new phone has the eSIM profile from the old device, just repeat the same activation steps on the new device to connect. This typically means heading into Settings, tapping on Cellular or Mobile Data, and selecting “Add Cellular Plan.” Your phone will automatically detect the eSIM you transferred and prompt you to finalize setup. Simply follow the on-screen instructions—it’s usually a quick confirm and you’re done. No need to scan a new QR code or contact your carrier again. Just stay in a good Wi-Fi area and you’ll be back online in seconds.

Manage Multiple eSIMs for Travel or Work

Juggling trips for work and leisure, I keep multiple eSIMs live on my phone simultaneously. To manage multiple eSIMs, you activate each one directly from your device’s mobile network settings, not by swapping physical cards. For example, before a business trip to Tokyo, I scan the QR code sent by my provider to activate eSIM for that region, then label it “Work Japan.” When a personal weekend in Berlin comes up, I repeat the process for a German travel eSIM, naming it “Trip Berlin.” In the settings menu, I can instantly toggle between them—my work line active for calls while the travel eSIM handles local data—all without ever needing to remove a physical SIM.

Store multiple profiles and switch between them remotely

For users needing different plans, modern eSIM tools allow you to store multiple profiles directly on your device and switch between them remotely via a settings menu or companion app. This eliminates the need to insert physical cards when changing from a work line to a travel data plan. Simply download and save each eSIM profile during activation; later, you can disable one and enable another without contacting your carrier. Remote switching works instantly, provided your device maintains a data or Wi-Fi connection to fetch the new profile’s credentials. Always verify your phone supports simultaneous profile storage before activating multiple eSIMs.

Use a secondary line for local data while roaming

When roaming, activate a secondary eSIM for local data to keep your primary number active for calls and texts. On your phone, assign the travel eSIM as your data line under Cellular settings, while your home line handles voice and iMessage. This prevents surprise bills and keeps work contacts reachable. Simply buy a local plan, scan the QR code, and label it “Data.” Toggling your primary line off for data is a quick way to avoid roaming fees entirely.

• Download the local eSIM via QR code or app before your trip to avoid connection issues.
• In iPhone settings, set your secondary line to “Default for Data” alongside “Allow Cellular Data Switching.”
• For Android, choose your roaming eSIM as the primary data SIM and disable data for your home eSIM.
• Verify your primary line is set to “No Data” under its own settings tab.

Delete unused eSIMs to free up storage space

After you’ve used an eSIM for a trip or an old work plan, delete it to free up storage space. Your phone’s eSIM memory isn’t unlimited, and crowding it can slow down future activations. Go to your device’s mobile network settings, select the inactive profile, and tap “Remove eSIM.” Clearing out old eSIMs prevents activation errors and keeps your list tidy. Most phones hold around 5–10 profiles; since you can only use two concurrently, a cluttered list is just waste. You’d be surprised how often a failed activation is cured by deleting a forgotten work eSIM. A quick spring clean of unused profiles keeps your next setup smooth.

Review Security and Privacy Settings

Before finalizing your eSIM activation, review security and privacy settings to lock down your digital identity. Navigate to your device’s carrier settings and confirm that SIM PIN protection is enabled—this prevents unauthorized use if your phone is lost.

A critical step is disabling “Allow eSIM Transfers” unless you explicitly need it, as this blocks remote cloning attempts.

Next, audit app permissions related to your new line; revoke access for any service that does not require cellular data to minimize tracking. Finally, ensure your iCloud or Google account backup excludes unencrypted eSIM profile details, keeping your network credentials safe from potential breaches. These actions seal your activation process against common privacy vulnerabilities.

Enable SIM lock or PIN to protect eSIM usage

Once your eSIM is active, immediately enable a SIM lock or PIN to block unauthorized usage if your device is lost. Navigate to your device’s SIM settings and set a strong, unique PIN for the eSIM profile. This ensures the eSIM cannot be reactivated on another phone without authentication. Enable SIM lock to protect eSIM usage as a first line of defense against theft. Always memorize your PIN or store it securely, as repeated incorrect entries may permanently block access.

Q: What happens if I forget my eSIM PIN?
A: You must use the PUK code provided by your carrier to unlock it; otherwise, the eSIM may become permanently disabled.

Turn off eSIM when not needed to avoid unwanted charges

After activating your eSIM, immediately configure a manual toggle within your device’s cellular settings. Turning off the eSIM line when not in use is essential to prevent carriers from billing for background data or unintended roaming. To disable it:

1. Open Settings > Cellular (or Mobile Data).
2. Select the active eSIM plan.
3. Toggle the “Turn On This Line” switch to off.

This step eliminates any risk of per-kilobyte charges while you are not actively using the plan. Only re-enable the line during your scheduled activation window.

Back up your eSIM profile or activation details in a secure place

Once you’ve activated your eSIM, don’t skip the step to securely store your activation details. Your carrier’s QR code, manual activation code, or install link is the only way to re-add the profile if you reset your phone or switch devices. Save a screenshot in a password manager or export the profile to a secure cloud vault—never just leave it in your email or photos. That small backup protects you from needing a new code from your carrier later.
