Is my Android device unlocked or locked by my provider?
When a device is locked (or “simlocked”), it means that you can only use a SIM card/eSIM profile from the carrier from which you bought your device.
To know if your Android device is locked/unlocked by your provider, go to : – Settings – General – About – Network Provider Lock : you will see in this field “NO SIM restrictions” or “SIM restricted”
In case you have “SIM restricted”, you just need to contact your carrier (from which you bought your device) and request the device to be “unlocked” (you just need to provide its IMEI that you can find under the Settings or dial *#06# to display it on your screen).
After that, your device will be unlocked automatically, and you will be able to use any SIM card and any eSIM profile on it.
NB : Please note that some devices are equipped with an eSIM, but you will not be able to use it, whether your device is locked or unlocked, as this eSIM feature can be restricted for some markets/countries. In this case, we advise you to contact the device manufacturer for more information.

The connection is steady and reliable
The connection is steady and reliable. I'm glad we have discovered Ubigi. We found the app and recommendations by using AI. The app is user friendly and easy to get going, like installing the e-sim. I also liked the point that when arriving at my destination my i-phone automatically shifted to the ubigi network. Main point is the international orientation which is convenient for future travel.

Great Service all over Japan

Easy service with good data quality
Easy service with good data quality. Buying and activating the esim was very easy. Although I had a small issue with activating my esim (because of a missing setting). Support was there to help! Would recommend.
