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

Tokyo Japan Trip 2026
We took our Vacation to Japan this year and assumed our phones would work there but no bueno. Meet a fellow American in the lobby who let us know about Ubigi. What a game changer! There are multiple plans which I find excellent for how long your stay will be. Not money gouging app where it’s just this or that. I will recommend Ubigi to all that will be traveling. Love the App. Simple and very fair $. Than you for making our trip ez

It was so easy to install the ESim
It was so easy to install the ESim. It all was done automatically and really quick. The connection worked right away with no issues since then. I have made other experiences with another supplier before, so I am very happy that it works so great with Ubigi now.

Used Ubigi whilst on holidays in Japan. Was so easy to load and use, internet connection was fast and never failed us thankfully as being old I was worried I would get lost easily. Will be using again on my next holiday
