I restored my data on my (new) iPhone, but my eSIM profile does not work. What to do?

When restoring your data to your a new or another iPhone, the eSIM profile is not restored. This is an Apple limitation in the data restoration process.

In order to properly reinstall your Ubigi eSIM profile on your iPhone after restoring or resetting your device, we invite you to follow the instructions below:

A/ If you are restoring or transferring data to the same iPhone:
Connect to WiFi or cellular data with your primary SIM card (locally), then follow instructions here to reinstall your Ubigi eSIM profile.

B/ If you are restoring or transferring data to a new iPhone or a different iPhone:
If you still have access to your “old” phone on which the Ubigi eSIM profile was installed, please access it and go to Settings to delete the eSIM profile on it. (NB: make sure you are connected to WiFi with old phone when deleting).

After that, follow instructions on this link in order to reinstall the eSIM profile on your new phone.

If you do not have access to your “old” phone on which the Ubigi eSIM profile was installed, please contact Customer Service mentioning the email address of your Ubigi account to help you resolve the situation.

Traveling from UK to Japan with Ubigi
As soon as I landed in Japan Ubigi was up and running and I didn’t have to worry about using my phone abroad. Thank you so much for the peace of mind this gave me.

Easy to use
It’s really easy to use and not expensive. The only problem is I sometime experienced short connectivity issues in big cities in Japon. Maybe that could be improved

Ubigi works!
We bought Ubigi for the first time for our Japan trip; I have to be honest, i was impressed it worked all the time! We were very happy with the service, never had issues on the subway, Shinkansen or even on the mountain of Kyoto of the monkey park! It would get signal everywhere!! The only time it slowed down was in the basement floor 2 while I was in the bathroom, but no issues anywhere else!

Ubigi surpassed my expectations
Ubigi surpassed my expectations. I used it in Japan and South Korea and the signal was great. I had high speed internet the whole time. It was my first time using it, and what I enjoyed the most about Ubigi is that I didn't need to install a new eSIM when I got to a different country. I kept the same eSIM, and I just change the plan on the Ubigi App. I feel this is such a great feature that is not advertised enough.
