I cannot connect with my Ubigi eSIM, what should I do?
First, make sure that your location is covered by our services here.
If this is your first connection, it might take a few minutes for the eSIM to connect.
If your location is covered but no network shows on your screen after few minutes, try the following troubleshooting:
– Check that cellular data (3G/4G/5G) are activated on your device (in the Settings) – Switch the device to “Airplane Mode”, then try to activate “Cellular” again – Restart your device – Do a manual network search: Select your Ubigi profile in Network & Internet, then go to “Mobile Network” and touch “Search Networks”. The list of available networks will be displayed, then select on that list one of our local partners (see the list here) – For Windows 10, Windows 11 & Android only: Check that roaming option is activated in the Settings

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.
