Customer Reviews

5 out of 5 stars
Japan

“The first time I used an international eSIM from this website with this company, I had no problems at all. I generally got 5G, and I was even in small towns in Japan—I honestly didn’t expect it to work that well.

I highly recommend it. To avoid any issues, and since it was 20GB, I disabled several apps so they wouldn’t use data in the background. By the way, I was also sharing it with my wife.

Everything was perfect.”

“Used without issues in both Tokyo and Osaka. The latency wasn't great due to roaming connection through Singapore, but was manageable. At least it’s more convenient than eSIMs that go through Hong Kong and don’t work with services like ChatGPT. The network was au’s LTE or 5G, and signal was solid everywhere, no complaints.”

“coverage was very good, easy setup at public wifi spot upon arrival. One major thing though: internet breakout is Hong Kong.

There is no instagram coverage (anymore) in Hong Kong!

If you plan to use this operator, you should be aware of this.”

“Had some trouble setting this up at first. The eSIM supports many of the major networks in japan (KDDI, NTT Docomo, SoftBank) and I had to manually force it to connect to Docomo before it would work.

On android: Settings -> Connections -> Mobile Networks -> Network Operators -> disable "select automatically"

After that, it worked flawlessly.”

“Used the 20GB, then the unlimited plan 5 day plan when I ran out. Both worked great.”
