Self Assistance - eSIM APN settings

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.

Excellent coverage whilst hiking in the Atlas Mountains. Fabulous coverage in Essaouira and Marrakesh. Fabulous value for money too. Never let me down 😀

seamless connection off the plane

Super seamless, got connected right off the plane. Used 10g between two people over 8 days pretty freely without having to worry about running out. I did find that the signal was poor in some areas of Uji, but other than that it was pretty reliable, even underground.

Works very well

Works very well, didn't give a 5 because I would have appreciated being able to choose the number of days : I was staying 4 days but only had choice between 1, 3 or 7. If you could make the lenght more personalizable it would be great

very high quality LTE connection.

You won't have to read instructions or guides online.

I don't like reading instructions. Using this SIM card was so simple and clear that I didn't have to read anything.

The most affordable pocket Wi-Fi on the market

We signed up with the Ubigi app for our current Japan land tour. We are thoroughly pleased with the service that Ubigi provides! My husband got a 15-day, 5g plan for only $10. He gave me a 20% referral discount for my purchase. I paid $8 for a 15-day, 5g plan. Combined, we paid only $18. Other carriers charge $10 per day. That plan would have cost us $130 vs $10. I text with my daughter in Hawsii daily. All text messages are delivered with absolutely no problem at all. We use Google Translate to translate from Japanese to English. It works like a charm! Thank you Ubigi for the excellent service that you provide and for keeping the cost low for the consumer! I am a “Happy Camper “ and then some!🥹❤️
