I get an error message when I use the QR code on my Ubigi account to re-install my Ubigi eSIM profile, why?
The error message below will be displayed in two cases:
1/ If the eSIM profile you try to re-install in a device is already installed in another device:
In this case, your Ubigi eSIM profile must be deleted on the first device before the re-installation on another device. If you do not delete your eSIM profile on the first device, the re-installation will not work (NB: this action won’t delete your Ubigi account).
If this deletion is not possible in case you don’t have your first device anymore (broken, lost, etc.), we invite you to contact our Customer Service for more help.
2/ Or if you already re-installed that same eSIM profile at least 5 times in the past on the same/or different devices:
All Ubigi eSIM profiles can be re-installed up to 5 times max after being deleted (NB: other providers usually allow the installation only once and re-installation is not possible).
This means that if you already did 5 re-installations in total for the same Ubigi eSIM profile (in same or different devices), it is no more possible to re-install it now.
Do not hesitate to contact our Customer Service for more help in case you want to keep your current Ubigi account and get a new Ubigi eSIM profile for it.

Good signal, app not great
The app was often not working and had maintenance so couldn't check how much I had left. But had good signal.

Saved money and stayed connected!
The connection was comparable to the connection of the country and the price great. I would have paid a fortune in roaming fees had I not utilized Ubigi. Glad my brother told me about it.

Most of the time it worked pretty well
Most of the time it worked pretty well; I had unlimited data for both Norway and Sweden, for one month each. However, I didn't have internet for two days in Norway and one day in Sweden, even though the signal was very strong.

Would recommend
Relatively easy to install when following the instructions.
I used an unlimited plan just to be sure to have enough for my work trip.
The connection was generally very good but I will deduct one star because sometimes it stopped working.

On arrival to Japan
On arrival to Japan, I received a notification to connect my sim, I made sure the sim was downloaded and showing on my phone before I left the Uk as previous experience with esims can be stressful if you arrive at your destination only to find out you cannot work out how to activate your travel sim. It is amazing to have the convenience of access to data and what’s app calls and google maps. So thank you Ubigi sim
