The Sony Xperia 1 VI smartphone is equipped with an eSIM.
Thanks to the eSIM, you will be able to use dual SIM cards. It means that the eSIM on Sony Xperia 1 VI allows you to immediately connect to another mobile operator without using a physical SIM card.
To activate your eSIM, you need a wireless service carrier which provides you an eSIM profile as well as data plans. eSIM data plans availability may vary depending on country and carrier. Ubigi is one of the carriers that support eSIM for the Sony Xperia 1 VI, in about 200 destinations, on the 5 continents.
The activation possibility of the eSIM feature might differ by country and/ or model version of the device. Ubigi is not responsible for this inconvenience.

Installation process can be tricky
Set up process/installation can be tricky. I was have to update the system on my phone, only then the eSIM started to work. I think Ubigi have to tell the customers about this possibility. I didn't know at first and spent a lot of time trying to connect with customer support to resolve the issue. If I knew in advance, everything would be much more smoother.

The best for high speed connection and reliability in Japan
I was traveling with a friend who decided to use their home plan for internet while I used Ubigi. Almost every time I had A 5G connection my companions only had an LTE Connection. Great coverage and great connection speeds everywhere I went in Japan and I never lost any connection.
