I scanned the QR code with my device but I got an error message. What should I do?

In case you get an error message when scanning the QR code to install your Ubigi eSIM profile, this may be because :
– your device is not eSIM compatible > you must use an eSIM compatible device to access Ubigi services
– your device is simlocked > contact the carrier you purchased it from to unlock it
– or you already scan your QR code more than 5 times > contact our Customer Support for further assistance.

Strong signal in rural Japan
Strong signal in rural Japan, and it’s easy to find an even stronger connection while on the subway. My experience using Ubigi has been very satisfying andI just hope the price can be kept more affordable. Thank you, Ubigi
