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

The ease of installing
The ease of installing would be the reason why I would use again. My reasoning for 4 stars (and not 5 ) was due to the fact that my dashboard claimed I had over 0.5g left, but I was not able to use anymore data.

Budapest and Ubigi
I have just come back from a trip to Budapest and wanted an E Sim for data instead of relying on Wifi. I decided Ubigi would be a good choice, and it was. I had a whole week's data for 9 euros. It was so good to be able to use it for Google Maps, and navigating the public transport system. I was impressed.

Great experience in Japan
I saw this eSIM mentioned in a few places and decided to give it a go. Used around cities in Japan and had no problems whatsoever. I'll use it again when I go back.

Good speed and coverage in east European countries. Not sure why Serbia is not in the program I purchased. It's the only one that has been excluded.

Really easy to set up & use
Really easy to set up & use. The data was fast to load & 99% of the time 5G during my stay in Spain. This is my 2nd time of using Ubigi & I'll definitely use them again for my next trip.
