I purchased another e-SIM provider, but ended up not being able to use it, not sure why, and that provider was helpful and ended up providing me with a refund. Then, I searched for which e-SIM provider is better to use in Japan, Ubigi pop-up, which I purchased. The connection was easy. I was worried that I couldn't get it connected because usually, I have my husband do that for me. However, surprisingly, it was very easy to connect. Good thing that it was connected just fine, so I won't feel lost without an internet connection, which I might not be able to connect with my family back home. Just a small piece of feedback is that sometimes I would lose the connections, but it will get back on again after a few minutes.

Installation was a breeze, but still a few minor issues
Installation was a breeze the first time! Top-up less so, it took a while to install the refill.
It was not easy to find how much data I had used. There was no warning the first time that I had run out, yet there was a notice just before the refill ran out. Odd....

I contracted Holafly for Japan and with 2 eSIM in 2 phones it did not work despite support trying to help. So I contracted Ubigi on the fly and it worked perfectly straight away, I also did live streaming without trouble. Completely recommandable.

A wonderful purchasing experience

2.Easy to set up and use.
3.Excellent after-sales service. I ran into a little hitch when activating the esim, so I contacted the after-sales service. I'm pleased that it solved within minutes. Awesome!
