Complete Guide to eSIM Installation on iPhone and Android

Installing an eSIM is straightforward, but the steps differ slightly between iPhone and Android. This guide walks you through the complete process on both platforms, plus troubleshooting for common issues.

Before You Start

Make sure you have the following:

• A compatible, carrier-unlocked device
• A stable Wi-Fi connection (you need internet to download the eSIM profile)
• Your eSIM QR code or activation details (provided after purchase)
• Sufficient battery life (at least 30%)

Important: Do NOT install the eSIM while connected to your destination's network. Install it while on your home Wi-Fi before traveling, then activate data when you arrive.

Installing an eSIM on iPhone

These steps apply to iPhone XS, XR, and all later models running iOS 16 or higher.

1. Open Settings on your iPhone
2. Tap Cellular (or Mobile Data in some regions)
3. Tap Add eSIM or Add Cellular Plan
4. Select Use QR Code
5. Point your camera at the QR code provided by MobiaL
6. Your iPhone will detect the eSIM profile — tap Continue
7. Wait for the profile to download (10-30 seconds)
8. Label the plan (e.g., "Travel Data" or the country name)
9. Choose whether to use this as your default line for data
10. Tap Done

The eSIM will appear under Settings > Cellular alongside your primary SIM. You can toggle it on/off and choose which line handles data, calls, and messages independently.

Installing an eSIM on Android

Steps vary slightly by manufacturer, but the general process for Samsung, Google Pixel, and other Android devices:

1. Open Settings
2. Navigate to Network & Internet (or Connections on Samsung)
3. Tap SIMs or SIM Card Manager
4. Tap Add eSIM or the + button
5. Select Scan QR code
6. Scan the QR code from MobiaL
7. Confirm the download when prompted
8. Wait for the profile to install
9. Name the eSIM plan for easy identification
10. Set your data preferences

On Samsung devices, you may also find the eSIM option under Settings > Connections > SIM Manager > Add eSIM.

Activating Your eSIM at Your Destination

Once you've installed the eSIM profile at home, activation at your destination is simple:

1. When you arrive, turn off Airplane Mode
2. Go to Settings > Cellular (iPhone) or Settings > Network (Android)
3. Enable the travel eSIM for mobile data
4. Disable data roaming on your home SIM to avoid charges
5. Your phone will connect to a local partner network within 30 seconds

Some eSIM plans activate automatically upon connection, while others activate on first use. Check your plan details for the specific activation policy.

Troubleshooting Common Issues

"Unable to Add Cellular Plan"

This usually means your device is carrier-locked. Contact your carrier to request an unlock, which is typically free if your phone is paid off. Alternatively, check that your device model actually supports eSIM — some regional variants don't.

QR Code Not Scanning

Ensure you're scanning from a screen (not a printout that's too small), in good lighting, and that your camera lens is clean. If the QR code still won't scan, most eSIM providers offer a manual activation code (SM-DP+ address and activation code) that you can enter manually.

No Network After Installation

Toggle Airplane Mode on and off. Restart your device. Ensure data roaming is enabled for the eSIM line (some travel eSIMs technically roam on partner networks). If the issue persists, check that you're in a coverage area for your specific plan.

eSIM Not Appearing in Settings

Restart your device. If the eSIM still doesn't appear, check if you've reached your device's eSIM profile limit (most devices support 8-20 profiles, with 2 active simultaneously). You may need to remove an old profile to add a new one.

Pro Tips

• Install your eSIM 1-2 days before departure so you can troubleshoot on home Wi-Fi if needed
• Take a screenshot of your QR code before scanning in case you need it later
• Label your eSIMs clearly (country + dates) if you travel frequently
• Keep your home SIM active for calls/texts while using the eSIM for data only
