Check eSIM profile activation
Check if your eSIM profile is activated on your device.
Apply data to eSIM profile
Ensure data is applied to your Ubigi eSIM profile.
Check APN configuration
Ensure that the APN is correctly set for your Ubigi connectivty.
Check network display
Check the network status for your Ubigi connectivity.
Final checks!
Check account creation and Internet access.
Now ensure that the Data roaming option is activated on your device.
Important: if you have carefully followed previous steps, mobile data must applied to your Ubigi eSIM profile (and NOT to your physical SIM card if you have one). This means that you won’t have extra roaming costs as only Ubigi rates will be applied while using the Ubigi cellular connectivity. In any case, always ensure that mobile data is applied to your Ubigi eSIM profile to avoid extra roaming costs while abroad.
Once you made sure you have applied mobile data to your Ubigi eSIM profile, go to: Settings > Connections > Mobile Networks > Activate data roaming.
In the same screen, select Access Point Names in order to check if the APN (Access Point Name) is set:
The APN is normally set automatically: mobiledata or mbb will appear in the list. In this case, you can go to the next step.
In case you do not see mobiledata nor mbb APNs, please follow these instructions to set the APN correctly. Once you created and selected the APN, you can go to the next step.

Superb for off road motorcycle Morocco
I was off on an off road motorcycle tour to the High Atlas in Morocco and needed good coverage and unlimited data - just in case.
The eSim download, sim switch and usage was faultless and superb coverage 5* in most areas. Actually better than my Virgin sim in Cheshire.
For the money is was complete peace of mind and a vital comms link.

Flawless
Flawless. Set it up before I arrived in Ireland. Switched over to the esim when I landed and it worked straight away.
I didn't realize it can't be used for local calls but that's not an issue for me as I just use an app instead.

Connection was pretty much spotless
Connection was pretty much spotless except for the first time I activated in JFK. I had to go connect to the airport wifi to reach my airport pickup but the rest of the way was perfect. Good value compared to other providers too.

Data has been great except when we’re in the car trying to listen to music off our phones. The data seems to drop and the music stops multiple times during one song.
