Here’s how to activate your eSIM in just a few minutes
Activating an eSIM is the process of digitally installing a cellular plan onto your device without needing a physical SIM card. You typically scan a QR code from your carrier or download their app, then follow on-screen prompts to complete the setup. This method offers the convenience of instantly switching or adding plans, eliminating the wait for a physical card to arrive.
Checking Device Compatibility for Digital SIM
You pull out your phone to activate the eSIM, but the first step isn’t tapping through a menu—it’s checking device compatibility for digital SIM. I remember fumbling with my settings, realizing that if your handset isn’t eSIM-ready, the entire activation process stalls before it begins. You must verify that your specific model—whether an iPhone XS or later, a recent Pixel, or a Samsung Galaxy S20 and up—supports it natively. Dig into «Settings > About Phone» to see if an IMEI for eSIM is listed, or scan your carrier’s online compatibility checker. Without that quiet confirmation, your QR code or activation link is just a dead end. This step saves you from a wasted trip to a store, ensuring your digital line goes live without a hiccup.
Confirming eSIM support on iPhone models
To confirm eSIM support on your iPhone for activation, navigate to **Settings > General > About** and look for the «Available eSIM» or «Digital SIM» label. Alternatively, dial *#06# to see if an EID number appears, which indicates eSIM hardware. Only iPhone XS, XR, and later models sold in the United States, excluding China eSIM the iPhone 14 and 15 series sold there which lack a physical SIM tray, include native eSIM capability. For compatibility check, verify your carrier supports eSIM activation on that specific iPhone model.
Confirming eSIM support on an iPhone requires checking for an EID in Settings or via *#06#, and ensuring the model is an iPhone XS or newer that is carrier-compatible.
Verifying eSIM capability on Android smartphones
To verify eSIM capability on an Android smartphone for activation, first dial *#06#; if an EID (Embedded Identity Document) number appears, the device supports eSIM. Alternatively, navigate to Settings > About Phone > Status and search for the EID. A sequential check ensures no steps are missed:
- Confirm the phone is carrier-unlocked and not a restricted model from a specific operator.
- Access Settings > Connections > SIM Card Manager; an «Add eSIM» option indicates compatibility.
- Check the manufacturer’s support page for the exact model number (found under Settings > About Phone), as only recent flagship and mid-range Androids, such as Samsung Galaxy S20 series and above or Google Pixel 3 and newer, include this hardware.
Without an EID or the «Add eSIM» option, the device cannot complete activation digitally.
Listing other devices that support embedded SIM technology
When checking device compatibility for your eSIM activation, it’s helpful to know that many gadgets beyond smartphones support this tech. Embedded SIM compatibility now extends to popular tablets like the iPad Pro and Galaxy Tab S series, as well as smartwatches such as the Apple Watch and Samsung Galaxy Watch. Several Windows laptops and Chromebooks with LTE also include an eSIM slot. Your car’s infotainment system or a cellular-based smart speaker might even be eSIM-ready, so always scout your device’s settings or manual for an «Add Cellular Plan» option before you begin the activation process.
Selecting a Mobile Carrier with eSIM Plans
When selecting a mobile carrier with eSIM plans, verify that the carrier explicitly supports eSIM activation for your specific device model, as not all providers offer this for all handsets. Check if the carrier provides a QR code or an in-app activation method, as this directly affects how you will install the eSIM profile. Pricing for eSIM plans often differs from physical SIM plans, so compare data and talk allowances for the same service tier. Once chosen, the activation process typically involves scanning the carrier’s QR code in your phone’s cellular settings or using the carrier’s app to trigger the download.
Some carriers require you to visit a physical store for initial eSIM provisioning, while others allow instant remote activation.
Ensure your phone is connected to Wi-Fi during the download, as the eSIM profile may be several megabytes in size.
Comparing major network providers offering eSIM activation
When comparing major network providers for eSIM activation, focus on how each delivers the QR code or app-based setup. T-Mobile lets you activate instantly through their app, while Verizon often emails a QR code that you scan under your phone’s cellular settings. AT&T typically requires logging into your account to generate the code. For a quick comparison, check the table below. The key difference comes down to activation method speed via each provider’s app—some let you start in two taps, others need a desktop step first.
| Provider | Activation Method | Steps to Start |
|---|---|---|
| T-Mobile | App-based | Open app, select eSIM, scan code |
| Verizon | Email / My Verizon | Log in, get QR, scan in Settings |
| AT&T | Online portal | Login, generate code, scan manually |
Identifying travel-friendly eSIM services for international use
When selecting an eSIM for travel, prioritize providers like Airalo or Holafly that offer regional data packages covering multiple countries. Check that the service includes pre-installed local profiles with instant activation upon landing, avoiding retail store visits. Confirm that the app supports QR-code installation and allows real-time top-ups via mobile data, not just Wi-Fi. Preload your primary eSIM before departure to test connectivity. Q: How do I verify an eSIM works in my destination country? A: Use the provider’s coverage map to confirm compatible local networks, then download the eSIM profile while you have a stable connection at home to avoid activation issues abroad.
Reviewing prepaid versus postpaid eSIM options
When picking an eSIM plan, think about prepaid versus postpaid options. Prepaid eSIMs let you buy data upfront with no contract—perfect for short trips or strict budgeting. Postpaid eSIMs bill you monthly, often bundling with perks like international roaming or unlimited data. Choosing prepaid for temporary use avoids long-term commitments. For activation, prepaid eSIMs usually offer instant QR codes after payment, while postpaid might require a credit check or waiting for approval. Postpaid can be cheaper per gigabyte if you use a lot of data each month.
- Prepaid eSIMs: pay once, activate immediately via QR code without tying to a contract.
- Postpaid eSIMs: receive a monthly bill and often get multi-device support or shared data.
- Check cancellation rules: prepaid expires when data runs out; postpaid may charge early termination fees.
- For activation speed, prepaid wins—no background checks or recurring billing setup needed.
Obtaining Your eSIM Activation Credentials
Before you start, you must obtain your eSIM activation credentials from your carrier. This typically comes as a QR code or a manual activation code, delivered via email or your online account portal after purchase. I remember fumbling through my inbox for the email titled “Your eSIM Details,” which contained both the QR and a 32-digit SM-DP+ address as backup.
Without these credentials—specifically the QR code or activation code—your device cannot download the eSIM profile to your phone’s eSIM slot.
Keep them handy in a secure note, because you’ll need to scan or enter them directly in your phone’s cellular settings to trigger the installation process.
Receiving a QR code from your carrier via email or app
Your carrier will send your unique eSIM QR code directly to your email or inside their app. Open the email or app notification, then download or screenshot the QR code to your phone’s photos. This code is your instant activation credential—no plastic SIM card needed. For a smooth setup, follow this sequence:
- Locate the QR code in your carrier email or app’s “eSIM settings” section.
- Save the image to your device’s camera roll for easy access during activation.
- Open your phone’s cellular settings and choose “Add eSIM” to scan the code.
Keep the QR code private; it’s tied specifically to your line and device.
Downloading the carrier’s mobile app for direct setup
For many carriers, your eSIM credentials are obtained directly through their proprietary mobile app. After installing the app on your existing device, you typically log into your account or create one. The app then automatically retrieves your eSIM profile. Direct app-based eSIM activation streamlines the process by eliminating QR codes. Follow this simple sequence:
- Download and install your carrier’s official app from your device’s app store.
- Sign in using your account credentials or register a new line.
- Navigate to the “Mobile Plans” or “eSIM” section and select the option to activate a new eSIM.
- Confirm the action; the profile will download and install automatically onto your device.
Manually entering activation details like SM-DP+ address
For eSIMs requiring manual setup, you’ll directly key in the SM-DP+ address provided by your carrier. This server string directs your phone to download the correct profile. Typically, you first navigate to your device’s cellular or mobile network settings, then select «Add eSIM» followed by «Enter details manually.» Next, input the SM-DP+ address exactly as given, often alongside an activation code. Double-check every character, as a single typo in the SM-DP+ address can block the entire download. After confirming, your phone connects to the remote server to fetch and install the eSIM profile.
- Locate the «Add Cellular Plan» or equivalent option in Settings.
- Choose «Enter Details Manually» or a similar prompt.
- Paste or type the SM-DP+ address and optional confirmation code.
- Tap «Next» or «Continue» to trigger the profile installation.
Steps to Install an eSIM on iPhone
To install an eSIM on your iPhone, first ensure you have a stable Wi-Fi connection. Navigate to **Settings > Cellular > Add Cellular Plan**, then scan the QR code provided by your carrier or enter the details manually. After labeling the plan (e.g., «Primary» or «Business»), tap **Continue**. The eSIM will activate automatically—often in under a minute. Q: What if the QR code won’t scan? A: Tap “Enter Details Manually” and input the SM-DP+ address and activation code from your carrier. Once added, confirm your line is active by making a test call. Your iPhone can store multiple eSIMs, but only one data line works at a time.
Navigating to Settings and tapping Cellular
To kick off your eSIM setup, grab your iPhone and head straight to the Settings cellular menu. Tap the app, then select «Cellular» (or «Mobile Data» in some regions). This is your command center for adding a new plan. Don’t worry if you see multiple options here; just look for the «Add Cellular Plan» button. That single tap is your gateway to scanning a QR code or entering details manually. If you don’t see it, ensure your device is unlocked and running the latest iOS.
Selecting Add Cellular Plan and scanning the QR code
After opening Settings, tap Cellular, then Add Cellular Plan. This action prompts the camera to scan the QR code provided by your carrier. The iPhone immediately reads the embedded activation data, parsing the SM-DP+ address and confirmation code. Precise alignment of the QR code within the viewfinder is critical to avoid scan failures. Once scanned, the eSIM profile downloads and installs automatically. If multiple plans exist, you can assign labels like “Business” or “Travel” for organizational clarity. The entire process replaces manual entry of long activation strings with a visual capture workflow.
Labeling your new plan and setting a default line
After activating your eSIM, you will be prompted to label your new plan and set a default line. Choose a clear label, such as «Business» or «Data Only,» to instantly distinguish it from your primary line in settings and calls. You must then designate a default line for iMessage, FaceTime, and cellular data. Select the line you intend to use for standard internet and communication services as your default. For voice calls, you can set a consistent default or choose «Ask Every Time» to manually select per call, ensuring your new eSIM integrates seamlessly without confusion.
Activating eSIM on Android Devices
To activate an eSIM on your Android device, first ensure you have a stable Wi-Fi connection. Begin by navigating to Settings > Network & internet > Mobile network or Add carrier, depending on your device. Select Download a SIM instead or scan the QR code provided by your carrier. If no QR code is available, you can manually enter the activation details, such as the SM-DP+ address and activation code. Some carriers may require installing a dedicated app first to initiate the eSIM provisioning process. After scanning or entering the details, follow the on-screen prompts to confirm the download and assign the profile to a specific line. The eSIM should activate within minutes, after which you can set your preferred network for data, calls, or texts.
Opening Settings and accessing Network & Internet
First, grab your phone and open the Settings app—it’s the gear icon on your home screen or app drawer. From there, tap on «Network & Internet» or «Connections,» depending on your Android version. This is your gateway to adding a new eSIM. Look for options like «SIMs,» «Mobile network,» or «SIM manager» inside that menu. You’ll typically see a plus sign or «Add carrier» button to start the setup. Just scroll down if you don’t spot it right away—some phones hide it under «Advanced» or «More settings.» Once you’re in, you’re ready to follow your carrier’s instructions for activating the eSIM.
Choosing Add Mobile Plan and scanning or entering details
After opening the eSIM section in your Android settings, choose Add Mobile Plan to proceed. You will be prompted to scan a QR code provided by your carrier, or manually enter the activation details like the SM-DP+ address and confirmation code. Ensure your camera focuses clearly on the QR code for instant recognition. Once the details are accepted, the eSIM profile will begin downloading to your device.
- Align the QR code within the on-screen frame for successful scanning.
- If the QR code fails, copy the SM-DP+ address and activation code exactly from your carrier’s email.
- Check that your device is connected to Wi-Fi while entering or scanning details.
- Verify the carrier name appears correctly after entering the details.
Completing the setup and switching data preferences
After scanning the QR code or entering the activation code, you must complete the setup by naming the eSIM profile (e.g., «Travel Data»). Then, navigate to **Settings > Connections > SIM Manager** to configure your data preferences. You can assign this eSIM exclusively for mobile data while keeping your physical SIM for calls, or set a preferred network for data roaming. Always ensure the eSIM’s data toggle is enabled. If you have two active lines, choose which line handles data to avoid unexpected charges.
Q: Can I switch which SIM uses mobile data without re-downloading the eSIM profile?
Yes. Go to SIM Manager, tap “Mobile data,” and select your preferred SIM or eSIM. The change takes effect immediately; no re-activation is required.
Activating eSIM on Wearables and Tablets
Activating an eSIM on a wearable or tablet requires a slightly different workflow than a smartphone. You typically initiate this through the carrier’s app on your primary phone, which then pushes the eSIM profile to the paired device. For standalone tablets, you often scan a carrier-provided QR code directly in the device’s cellular settings. The main concept is that the wearable acts as a dependent device, most frequently sharing a number from your primary phone line, whereas a tablet can have an independent data-only plan. A critical step is ensuring your device is fully updated and on a stable Wi-Fi connection before scanning the QR code or starting the app setup, as the process cannot be interrupted.
The key insight is that while a smartphone eSIM activates the device itself, a wearable eSIM activates a connection to your phone’s existing service, making the phone a mandatory part of the activation process.
Pairing a smartwatch with its companion smartphone app
Pairing a smartwatch with its companion smartphone app is the first practical step before an eSIM can be activated for cellular service. Ensure the smartwatch is charged and near the paired phone. Open the dedicated companion app (e.g., Apple Watch app or Galaxy Wearable) and follow on-screen prompts to establish a Bluetooth connection. Once paired, the app typically presents an option to set up a mobile data plan. You will then follow a specific sequence: selecting the network provider, scanning a QR code sent by the carrier, or entering an activation code. This app-based pairing is the gateway to completing the eSIM provisioning process. The companion smartphone app manages the entire activation workflow.
- Power on the smartwatch and place it next to the phone.
- Open the companion smartphone app and select “Pair new device.”
- Confirm the pairing code displayed on both screens.
- Navigate to the eSIM or mobile data setup section within the app.
- Enter the carrier’s eSIM details as prompted.
Using a tablet’s built-in eSIM manager to add a plan
To add a cellular plan via a tablet’s built-in eSIM manager, navigate to the device’s settings menu, typically under “Cellular Data” or “Mobile Network.” Select “Add eSIM” or “Add Cellular Plan,” and the system will scan for available networks. You can then choose to scan a QR code provided by your carrier or manually enter the activation details. Once confirmed, the plan downloads directly onto the tablet’s eSIM chip. This method bypasses the need for a physical SIM card, letting you manage multiple data plans within the same interface. After installation, label each plan for easy switching between profiles during travel or work. Finally, toggle the new plan’s data slider to “On” to begin using the service immediately.
Verifying connectivity after wearable provisioning
Once provisioning completes, you must confirm the wearable appears independently on your carrier’s network. Open the wearable’s settings and locate the cellular or mobile data toggle; switch it to the active position. Perform a test call or send a message from the device itself, not the paired phone. If data isn’t flowing, quickly toggle Airplane Mode on and off to force a fresh network registration. This post-provisioning connectivity check ensures the eSIM profile is live, not just saved. A successful test means your wearable now operates as a standalone connected device.
After provisioning, verify connectivity by toggling cellular data, placing a test call, and forcing a network re-registration to confirm the eSIM is actively working.
Troubleshooting Common eSIM Activation Issues
When activating an eSIM, the most frequent issue is a «No Service» error, often resolved by ensuring your device is unlocked and connected to Wi-Fi. If the eSIM profile fails to download, restart your phone and try again. Carrier settings may need updating via your network menu. A common question: Why does my eSIM show «Activation Pending»? This typically occurs if you removed the eSIM before downloading the profile or if the QR code expired; request a new one from your carrier. For dual-SIM setups, verify that the eSIM line is enabled in your cellular settings. After installation, if the network drops, toggle Airplane Mode on and off. Always confirm your phone’s IMEI is eSIM-compatible with your carrier.
Fixing QR code scanning failures
When a QR code fails to scan during eSIM activation, first ensure the screen displaying the code is clean and at full brightness, with no reflections. Hold your device camera 4–6 inches away, using your phone’s native camera app rather than third-party scanners. If the code remains unreadable, manually enter the SM-DP+ address and activation code provided by your carrier through your device’s cellular settings menu. Restarting your phone can also clear temporary software glitches that prevent the camera from parsing the QR data correctly.
Resolving network registration errors
If your eSIM activates but shows «No Service,» you’re likely facing a network registration error. First, toggle Airplane Mode on for 30 seconds, then off—this forces a fresh network handshake. Manually selecting your carrier under Cellular Network settings often overrides a failed automatic registration. Sometimes a simple reboot triggers the eSIM profile to re-register with the tower. If errors persist, re-insert your physical SIM temporarily to re-establish network sync, then remove it. Ensure your carrier’s APN settings match their documentation exactly.
Resolving network registration errors requires forcing manual network selection, rebooting, and verifying APN accuracy to complete eSIM activation.
Managing dual SIM conflicts between physical and eSIM
When activating an eSIM, a physical SIM often remains inserted, creating dual SIM profile priority conflicts. The phone may default to the physical SIM for data or calls, leaving the eSIM inactive. To resolve this, manually designate the eSIM as the primary line for cellular data in network settings. Additionally, ensure the device’s dual SIM mode supports simultaneous active connections, as some require disabling one line. If activation fails, temporarily remove the physical SIM to isolate eSIM provisioning, then reinsert it. Finally, verify that no carrier-imposed restrictions limit eSIM functionality when a physical SIM is present.
- Set the eSIM as the default data line in mobile network settings.
- Check device compatibility for concurrent physical and eSIM usage.
- Test activation with the physical SIM removed to rule out interference.
Managing Multiple eSIM Profiles on One Device
Managing multiple eSIM profiles on one device hinges on activating each profile correctly. Your device’s settings menu acts as a central hub where you activate a new eSIM by scanning a QR code or entering a code, but you can store several profiles simultaneously—often labeled as “Primary,” “Secondary,” or custom names for work, travel, or local data. After activation, you must designate which profile handles voice, SMS, and data, or set one as the default line for each function.
You can also toggle profiles on or off without deleting them, enabling you to swap active lines in seconds for specific trips or tasks.
This flexibility means a single device can seamlessly juggle a personal number, a business line, and a temporary data plan, all from the same activation workflow.
Storing several plans and switching between them
Storing several plans on one device relies on the device’s ability to retain multiple eSIM profiles, each tied to a different carrier. Seamless profile switching is managed through the device’s settings menu, typically under Cellular or Mobile Data, where you can label each plan (e.g., Work or Travel). You toggle between them by selecting the active line for data or calls without removing other profiles. This avoids physical SIM swaps but requires ensuring the primary line remains as the default for iMessage or calls. Dual-SIM status must be verified for compatibility, as some models only support one eSIM active at a time.
Deleting an old eSIM profile to free up space
When your device’s eSIM storage is full, you must delete an old eSIM profile to free up space before activating a new one. Navigate to your device’s mobile network settings, locate the list of installed eSIM profiles, and select the inactive or obsolete profile. Tap “Remove” or “Delete eSIM,” then confirm the action. This instantly reclaims storage, allowing the new eSIM activation to proceed without a storage error. Be certain you no longer need that profile, as deleted eSIMs cannot be recovered without a new QR code or activation code.
Deleting an old eSIM profile frees storage space, enabling activation of a new eSIM when device capacity is reached.
Setting primary and secondary data lines for travel
When traveling, assign your home network as the primary data line for eSIM travel to keep your number active for calls and SMS, while activating a local data plan as the secondary line for internet access. In your device’s cellular settings, toggle “Allow Cellular Data Switching” so the device automatically uses the secondary line for data when the primary signal fails. This dual-line setup eliminates roaming fees and prevents your home provider from billing for foreign data usage. Confirm the secondary line is set to “Use as Data Line” before departure to avoid unexpected charges at borders.
Setting primary (home) and secondary (local travel) data lines ensures cost-free roaming and uninterrupted connectivity.
Transferring eSIM to a New Phone
Transferring an eSIM to a new phone is essentially a reactivation process. First, you’ll usually need to delete the eSIM profile from your old device in the cellular settings—this frees the line for transfer. Then, on your new phone, you activate the eSIM by scanning the same QR code your carrier originally provided, or by downloading a new profile from their app. Your carrier’s account portal is the key hub for this; you can often trigger a fresh QR code or a one-time activation link there. If the QR code isn’t working, manually entering the SM-DP+ address is a solid backup. Some carriers let you transfer instantly via a simple confirmation text, which feels almost like magic. Once the profile is installed, just ensure cellular data is toggled on. Don’t wipe your old phone until the new one shows an active signal on the network.
Removing eSIM from the old device via carrier app or settings
Before activating eSIM on your new phone, you must first remove it from the old device to free the profile. The simplest route is through your carrier app’s eSIM management menu, where a “Remove” or “Delete eSIM” button typically appears. Alternatively, navigate to Settings > Cellular/Mobile Data, select the eSIM line, and tap “Remove Cellular Plan.” Follow any on-screen confirmation prompts. Here’s the standard sequence:
- Open your carrier app or phone Settings.
- Find the active eSIM under cellular plans.
- Tap “Remove” or “Delete Plan.”
This disassociates the eSIM from the old device, enabling a clean transfer and activation on your new handset.
Reinstalling eSIM on the new device using previous credentials
If your eSIM was previously installed, reinstallation on your new device typically requires using the same login credentials from your original carrier account or app. Navigate to your carrier’s eSIM management section, select the option to redownload or transfer the profile, and authenticate using your existing username and password. The carrier may send a one-time verification code to your registered email or phone number. This avoids requesting a new QR code. Ensure your old device’s eSIM is deactivated first to prevent conflicts. Reinstalling eSIM using previous credentials often works when migrating between compatible devices on the same account.
Reinstalling eSIM on a new device using previous credentials involves logging into your carrier account to redownload the profile after authenticating and deactivating the old device.
Contacting support if automatic migration fails
If automatic eSIM migration fails, immediately contact your carrier’s support team. Provide your account details and the QR code or activation code from your original eSIM installation. Support will remotely reissue a new eSIM profile to your new device; this process often requires confirming identity via a one-time passcode. Do not delete the original eSIM until support confirms it is safe, as this can block reactivation. Some carriers offer in-app support chat for faster resolution, while others require a phone call.
Security Tips for eSIM Users
When activating an eSIM, always obtain the QR code or activation code directly from your carrier’s official app or verified website to avoid phishing scams. Never share your activation code or QR screenshot with anyone, as it can be used to clone your eSIM. Use a secure, password-protected Wi-Fi network during activation, not public hotspots, to prevent interception. After activation, immediately delete the QR code from your photos and messages.
If your device is lost or stolen, contact your carrier to remotely suspend the eSIM profile to prevent unauthorized use.
Store the carrier’s emergency deactivation number in a separate, offline location.
Locking your eSIM line with a PIN
Once your eSIM is activated, immediately lock your eSIM line with a PIN to block unauthorized cellular usage if your device is lost or stolen. This PIN, separate from your phone’s screen lock, prevents anyone from using your eSIM profile for calls, texts, or data without entering the code. Activating this is practical during setup: navigate to your device’s “SIM & Mobile Network” settings, select the eSIM line, then enable “SIM Lock.” Enter a unique, non-sequential PIN you can remember. Without this lock, a thief can simply swap your eSIM to another device—instantly incurring charges or accessing your accounts. Secure it now.
Backing up activation codes in a secure location
When you activate your eSIM, always back up the QR code or activation code immediately. Since losing your phone or switching devices requires re-downloading that code, save a screenshot to an encrypted cloud folder or print a physical copy kept in a safe. Secure eSIM backup storage prevents being stranded without mobile service. Just ensure the printed version is fireproof and stored away from prying eyes.
Treat your eSIM activation code like a physical SIM card holder: store a backup in a locked, offline spot to avoid activation headaches later.
Disabling remote provisioning when not needed
Disabling remote provisioning when not needed is a critical step after activating your eSIM. Once installation completes, revoke this function in your device settings to block unauthorized profile downloads. This prevents malicious actors from pushing a rogue eSIM profile onto your phone if it’s lost or compromised. For example, on iPhone, toggle off “Add eSIM” under Cellular settings; on Android, deactivate “Remote provisioning” in SIM manager. A dormant eSIM slot is safe, but live provisioning access is a backdoor you don’t want. Secure your eSIM by disabling remote provisioning the moment activation finishes.
Q: How do I disable remote provisioning after activation? A: Immediately open your device’s mobile network settings, find the eSIM or SIM management menu, and toggle off options like “Add eSIM remotely” or “Download new profile.” This locks the slot so no one can install a new eSIM without your physical device.
Understanding the Basics of eSIM Activation
What an eSIM Actually Is and How It Differs from a Physical SIM
