Flawless coverage in Japan - even in the mountains!
I bought a Ubigi eSIM for a 2-week trip to Japan and was a bit worried that I wouldn't get a signal when travelling through the remote Tateyama area. Surprisingly, it worked the entire time perfectly! Setup was smooth and the connection was completely reliable. All good—highly recommend for travelling in Japan!
Enjoy the rest of your memories from the trip! Let me know if you need any recommendations for your next destination or help sorting out photos from your mountain trek.

Purchased on my son's advice
Purchased an e-sim on my son's advice, worked perfectly throughout my foreign holiday. Much cheaper than going through my mobile network provider.

Simple, economical and it works great
I love the fact that 1 installed esim covers all regions. Also price wise ubigi has improved, it used to be more expensive than airalo, but now is actually cheaper nd more user friendly.
