The Sony Xperia 1 IV 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 IV 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 IV, in about 190 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.

Save Your Time and Get Ubigi's eSim.
My friends & I went to Japan again. I decided to try out Ubigi eSim this time while my friends went with with using a pocket WiFi again. So I could give you a few comparisons between the two on our trip. First off, I was able to activate and use my connection once we landed. My friends had to pick up their pocket WiFi at the airport in order to get connection. Throughout the trip, I had more space in my bag while my friends had to carry their pocket WiFi around. I also noticed that my friends had the inconvenience to charge their pocket WiFi once in a while whenever we are on the go. I didn't have to worry about that.
I was speculative about using an eSim because Reddit users talked about losing connection in certain areas. I didn't have that trouble. I did notice some areas where I had LTE but my connection was still strong. I was able to call, text, and use the internet all around. I did notice my battery dies faster but I'm not sure if it was because of the eSIM or because I used my phone a lot.
Overall, I highly recommend Ubigi's eSim. I'm sure my friends will transfer over to an eSim the next time we travel to Japan.

Need to update your GPS
Need to update your GPS. Booking pick-up at the wrong number. The car waiting at few yards away from pickup address. It’s not helpful when you have difficulty to walk. Over charged by 2/3 of the fair display on the selected.

Solid
Solid. I used Ubigi in Tokyo, Japan for 7 days and it worked as well as I expected. There were some moments where I could not get a connection but they were few and far between. Solid. 4/5

I’m so impressed and was so relieved to be able to get online. It meant I was able to do my emails while in South Africa. Plus access to 5G baby 🤩. The speed was insane 😁. I was really pleased after being disappointed that my network Three doesn’t give what they say they would on my contract. Ubigi came to the rescue. Thank you 🙏🏾

It was easy to purchase and set up
It was easy to purchase and set up. I like how the app provides your current usage and the expiry date. Very easy and user friendly. I will definitely recommend and use it again in the future.

Easy, simple, good value
Very clear instructions, user friendly, and very simple. Loved how the eSim was automatically added to my phone and I just had to turn it on, and my primary eSim off. Good value for my week in Japan where having data and using the Translate app was essential.
