My eSIM Ubigi profile is installed and active on my iPhone/iPad, the network is displayed but I don’t have access to the Internet, what should I do?
Important: When you have multiple SIM cards/eSIMs (“plans”) on your iPhone/iPad, it is not possible to activate cellular data on two plans at the same time. You can only apply it to one of them.
You need to verify that Cellular Data is applied to the Ubigi eSIM profile for you to access the Internet. To do that, go to:
– Settings:
– Then, select Mobile Data:
– Then, select Mobile data again:
– Finally enter Cellular Data and select “secondary”:
Your iPhone/iPad will now use the cellular data connection from your Ubigi eSIM profile and you will be able to access the Internet with it.

Good basic plan choices and Easy to setup
Great setup experience and good range of general plans. One big gripe however is the lack of big data plans as most seem geared up for low use travellers and not data consumers. There are some unlimited packs if you dig deep, but they seem rare.

Best Travel ESim by far!
Absolutely brilliant! My husband and I have used other esims for trips before but they have been difficult to enable. Ubigo is so easy to use, easy to purchase and load, connecting automatically when we swapped countries, great value and great reception everywhere. Now we have the app we will definitely use for all future vacations. Highly recommend.

Was skeptical of the reviews but everyone recommended this and it’s awesome! High quality service with bars everywhere in Japan even Koyasan! Got 25gb for 3 weeks and was enough if I downloaded maps before leaving!
