I bought a Ubigi eSIM profile, but my phone is SIM-locked and I can’t install the eSIM profile. What should I do?

If your device is locked by the carrier you purchased it from, you won’t be able to install a Ubigi eSIM profile until the device is unlocked. To unlock it, contact your carrier and request an IMEI unlock (you will need to provide your device’s IMEI, which can be found in your phone’s settings).

Once your device is unlocked, you will be able to scan the QR code you received by email to install your Ubigi eSIM profile.

Note: Some devices have eSIM functionality but may not support it in certain markets or countries, even if the device is unlocked. In this case, we recommend contacting the device manufacturer for more information.

Ubigi was a lifesaver
Ubigi was a lifesaver. I had the free 3 day world eSIM. It was almost unbelievable how easy it was to activate and use the eSIM. I would recommend Ubigi for a peace of mind as I could start the plan in my home country and activate it once I reached Tokyo. Asshamed to say that my planned eSIM for my 14 day trip had so many errors that I wasted almost 2 days solving the issue with the vendor.

I have found Ubigi the best and most efficient eSIM for traveling through Asia and Europe. I’m a retired senior and discovered Ubigi for Japan and since then have given dozens of detailed and confirmed recommendations to other international travelers on Facebook. You have seen that by how many times I gave my reference discount code out.

This eSIM works perfectly
This eSIM works perfectly. Set it up before I left Australia and activated it when I arrived in Japan. It hasn’t missed a beat. I would definitely use Ubigi again on my next overseas trip.
