An eSIM is a SIM card that is embedded in a mobile device and can connect you to any operator offering eSIM services.

Furthermore, the e-SIM works the same way as a traditional SIM card, but you don’t need a physical SIM card to use it. It is actually pre-installed in the device and you can activate it by installing the “eSIM profile” of a new operator.

Actually, it is an evolution of the physical SIM card. More and more smartphones, tablets and laptops are equipped with an eSIM card.

To use Ubigi, your device must support eSIM technology. Compatibility depends on your device brand (Apple, Samsung, Google, etc.) and the model/version you own.

There are 3 easy ways to check if your device is eSIM compatible:

1. Dial *#06#
If an EID number appears on screen, your device supports eSIM.
No EID? Your device likely isn't compatible.

2. Use the Ubigi app
Open the Ubigi app on your device.
If it's not eSIM compatible, you’ll see an error message letting you know that eSIM isn’t supported. We’ll be happy to welcome you back when you switch to an eSIM-compatible device.

3. Check our compatible devices list
Search your device in our regularly updated list of eSIM-compatible devices.
Reminder: Your device must also be carrier-unlocked to activate an eSIM from Ubigi.
Devices bought from mobile operators may be locked and unable to install third-party eSIMs.

To access the Ubigi connectivity and connect to Ubigi services, you must first be equipped with an eSIM compatible and carrier-unlocked device.

No, Ubigi eSIM is data-only. However, you can make calls and send messages using apps like WhatsApp, FaceTime, Skype, Teams, Messenger, and other VoIP services. For traditional calls and SMS, you keep your primary provider and your phone number, allowing you to stay reachable while using Ubigi for data.
