Frequently asked questions about the Apple Watch Series and eSIM

Yes: the Apple Watch Series is fully compatible with eSIM and works perfectly with our app that sells eSIMs. You can download, purchase, and install your eSIM directly through the app.

Yes, if your carrier and model allow it. the Apple Watch Series supports the "nano-SIM + eSIM" (Dual SIM) configuration in many countries. This allows you to keep your primary number while adding an eSIM, for example for travel.

The validity period of an eSIM depends on the plan chosen and the activation method. In general, it begins when you first connect to the local operator's network. To ensure a smooth trip, we recommend activating your eSIM one week in advance. This will allow you to verify that everything is working properly and avoid any unexpected issues.

You can activate up to 1 eSIMs on the Apple Watch Series. However, it can store up to 2 eSIM profiles.

Go to your Apple Watch Series in Settings → Cellular (or Mobile) → Add an eSIM plan. If this option appears, your Apple Watch Series is eSIM compatible. If not, check that iOS is up to date and that your device is unlocked.

Yes: the Apple Watch Series is fully compatible with travel eSIMs. Buy an eSIM for your destination from our app, activate it before departure and keep your main SIM active: you use mobile data abroad without roaming charges while keeping your number.

No: travel eSIMs are linked to the device on which they have been installed. Once activated on the Apple Watch Series, an eSIM cannot be moved to another phone. If you change handset, you will need to purchase a new eSIM for your new phone.

Yes: unlike a physical SIM, an eSIM cannot be removed or cloned in the event of theft. Its activation requires cryptographic authentication with the operator, and the data is stored in a secure chip embedded in the Apple Watch Series, making SIM swapping attacks considerably more difficult.

Yes, if you switch to an eSIM with your main operator, your number is retained: your operator provides you with a QR code to scan from the the Apple Watch Series settings. Travel eSIMs in our application do not contain a phone number: they are used for mobile data only, and complement your main line.

The eSIM remains associated with the lost device and cannot be transferred. Block your phone and contact your operator to suspend your main line. For a travel eSIM purchased via our application, contact our customer support team, who will examine your situation on a case-by-case basis.
