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.

Very smooth experince. It worked flawlessly as turned on. Since I first met with Ubigi last year, I do not use any other e-sim provider. Keep with the good work.

Recommended, Good coverage around Japan
Slight misunderstanding when following instructions to activate the ESIM since it did not activate upon arrival. I went back to read the instructions again and found that I missed a step. No other issues were noted as it worked well through out my stay in Japan.

Pretty good overall
Pretty good connection throughout our trip- cities and country side- Mt Fuji, Shiminami Kaido, only very occasionally has not so good connections, but it was a struggle to get it started after we landed in Osaka, we had some nice Ninja Simcard employees helped us:)
