Activation on iOS.

In the ZIM@SBB app, you can find a tutorial which takes you through the eSIM installation and activation step-by-step.

After you purchase a data package, you can install the eSIM directly via the installation link in the app wallet. This is the easiest option. Tap on the link and follow the instructions on your device. You will be automatically guided through the installation process.

If you would like to carry out the installation via QR code or manually, you can find the relevant instructions below.

If you would like to activate your eSIM by scanning a QR code, follow these instructions:

Note: To scan the QR code with your smartphone or tablet, you need a second screen or device displaying the QR code for you to scan. If you do not have a second device available, please follow the manual instructions (see further down the page).

Step 1.

After purchasing your eSIM plan, you receive an e-mail with a QR code. Download the QR code and scan it.

Step 2.

Customise your plan according to the instructions.

Step 3.

When you arrive at your destination, make sure that you have set ZIM@SBB as your default line for data.

Do this by going to ‘Settings’ → ‘Mobile Data’ → ‘Mobile Data’ again → ‘ZIM@SBB’.

Step 4.

Don’t forget to turn on data roaming for ZIM@SBB and make sure that the data roaming for your primary SIM card is turned off.
