Reviews
the sim card worked great. I've been expanding it and there were no glitches. I took 20 GB for 14 days. I still have 8 GB unused. I definitely recommend it.
I bought this 20gb esim for two weeks in Japan and I have 12 giga left despite the intensive use of the phone with Google Maps, social and messaging apps. I had initial problems that continued to lose the signal, to solve I recommend changing the esim profile settings the "Operator" item uncheck automatic selection and manually select SoftBank as the operator.
Please check first if your smartphone is on the list. It is a bit confusing to activate but then it works perfect!
This was great! we stayed for 13 days and got 20gb and still had over 10gb when we left. Easy to install and use. Will definitely be using it again!
good. but please read the instructions good when. installing the esim. at arriving please give it a few minutes to connect
ESIM is amazing , working straight away when landing on Japan .
roughly u need 1gb/day provided u use google maps a lot.
It's easy to connect, you can do it before departure. Everything connected successfully. The Internet is fast.
Good, smooth to use, much more convenient than traditional physical sim cards, and you can check the remaining data at any time and top up at any time
Mostly good network coverage. A little worse in large crowds, sometimes you hardly have any reception
