Ubigi eSIM -Excellent
Ubigi eSIM was a bit of a challenge to set up initially, and it did require some patience to get everything running. However, once it was activated and working properly, the service was absolutely flawless.
Throughout my Far East trip, the data connection was reliable, fast, and consistent, with excellent signal coverage across multiple locations. It completely removed the stress of finding local SIM cards or relying on unreliable Wi-Fi, making travel far easier and more comfortable.
Once up and running, it delivered exactly what you want when travelling: seamless data access, strong coverage, and peace of mind. I would confidently use it again for international travel.

The app was straight forward and price isn’t too bad considering coverage. I have used this with no issues in Japan and Philippines. I highly recommend it.
