What is an eSIM profile ?

An eSIM profile is the software that you must download to your eSIM-enabled device to access the carrier’s mobile network. It is different from a conventional SIM card that is a physical card inserted into a device and that is removable.

To install the eSIM profile on your device’s embedded eSIM, carriers usually provide one of the following options:

– A QR code (or activation code) that you scan with your device for automatic installation

– Automatic installation of the eSIM profile, either:
> via the carrier’s app, or
> through a deeplink provided by your eSIM carrier

With Ubigi for example, you just need to follow the step-by- step guide here to install your eSIM profile automatically from the Ubigi app depending on your device.

Very good connection

Very good connection which is the most important. I just had some difficulties in activating it as it hasn't connected automatically when I was at place as it was supposed to do.

The entire family used the Ubigi eSIM…

The entire family used the Ubigi eSIM for a week white in Tokyo Japan, and it worked flawlessly. Much better than Airalo. Actually 1 of the 4 family members on the trip had Airalo, and Airalo stopped working after day 2. He ended up switching to Ubigi. We would not have been able to navigate out way in Tokyo with the Ubigi’s reliable service.

Diverse plan

I hope you’ll have plans for 5 days unlimited. I only used for 5 days and there are no options. Or something like we can choose how many days and there is a day rate

Good experience

Good experience, thank u for support to be connected with the world

Easy to use and ready as soon as we got off plane.

Got the ESIM before we took the plane to Japan. Once we landed and turned it on service has been great. Very easy to turn on just check their instructions and turn your main service line off( so your phone isn’t trying to use both. Can still text/call with WhatsApp/fb messenger/ iPhone. Would def recommend
