Ubigi is a data-only service, allowing you to use messaging apps such as WhatsApp, Skype, Viber, Telegram, WeChat, LINE and Facebook Messenger for calls and texts.


Our eSIM data plans work on any eSIM-enabled, network-unlocked device, so you can keep your physical SIM card (and your usual WhatsApp / Viber / Telegram number...).


Here's how it works:

Monthly data plans cannot be purchased on the website but directly in the Ubigi app for smartphones or on ubigi.me for laptops. See more information about purchasing a monthly data plan.

    Ubigi eSIM data plans work on eSIM-enabled and network unlocked devices.

    To check if your device is eSIM compatible, follow these steps:​

    Dial *#06#. If you have an EID code on the screen, your phone is eSIM compatible.

    To check if your iPhone/iPad is locked or unlocked by your provider, follow these steps:​

    • Go to Settings.
    • Select General.
    • Choose About/Information.
    • Scroll down to Network provider lock/Carrier lock. You will see either "No SIM restrictions" or "SIM restricted" in this field. Check here what to do if you have "SIM restricted".

    To check if your Android device is locked or unlocked, please contact your original carrier. (You can also test using a different carrier in your home country, which is usually not possible with a SIM-locked device)
