Activating your eSIM

Setting up your JetSim eSIM is quick and straightforward. You have two installation options: scanning a QR code for the fastest setup or entering details manually if needed. Follow the steps below to be online in no time.

Installing your eSIM via QR code

The easiest and recommended way to activate your JetSim eSIM. What you need:

• On a separate device (laptop, tablet, or another phone), open the email from JetSim containing your eSIM QR code.

2. Scan the QR code

• On your iPhone, go to Settings > Cellular (or Mobile Data) > Add eSIM. This will take you to the ‘cellular screen’ where you can manage your cellular plans.
• Tap Use QR Code and scan the code.

3. Follow the setup instructions

Quick tips for a smooth setup

Before you start the installation process, a few key checks will ensure everything runs smoothly. Here’s how to get your JetSim eSIM up and running on your iPhone:

1. Check your iPhone’s compatibility

Not all iPhones support eSIM, so before purchasing a JetSim plan, verify that your device is compatible. JetSim eSIM works with iPhone XS, iPhone XR, and iPhone XS Max models, as well as new iPhone models, including the iPhone 15 series.

Not sure if your iPhone supports eSIM? Check out our eSIM compatibility guide to confirm your device is ready.

2. Make sure your iPhone is unlocked

Your iPhone must be carrier-unlocked to use an eSIM from JetSim or any other provider. To check, go to Settings > General > About and look for Network Provider Lock. If it says “No SIM restrictions”, your device is unlocked and ready for eSIM activation. If your iPhone is not unlocked, contact your carrier to assist with unlocking the device.

3. Stay online during installation

A stable Wi-Fi or mobile data connection is essential for activation. If your internet drops during setup, the installation may fail, requiring you to restart the process.

4. Don’t delete your eSIM once installed

Once your JetSim eSIM is activated, avoid deleting it unless absolutely necessary. If removed, you’ll need a new activation code to reinstall it. Need to switch plans? Instead of deleting your eSIM, go to Settings > Cellular > Select eSIM > Turn Off This Line. You can always reactivate it when needed.

5. Enable Data Roaming for international travel

For your JetSim eSIM to work correctly, Data Roaming must be turned on. Go to Settings > Cellular > [Your JetSim eSIM] > Data Roaming > Toggle On.

6. Keep your JetSim app updated

Ensure your JetSim app is up to date to avoid any software bugs that might interfere with activation. Updates often include important fixes and improvements for a smoother experience.

The takeaway

Setting up an eSIM on your iPhone is simple, giving you instant access to mobile data without the hassle of physical SIM cards. Whether you’re switching networks or preparing for your next trip, a seamless eSIM setup keeps you connected in just a few taps. With JetSim, you get flexible plans, reliable coverage, and an easy activation process – so you can focus on exploring, working, or staying in touch without interruptions.
