It worked perfectly fine in Japan
It worked perfectly fine in Tokyo, Osaka and Kyoto. I only lost signal in the Shinkansen but I guess that's normal. 10/10 would recommend

Seamless Use throughout Japan
From purchasing, activating and using, this was extremely easy. The tutorials on the website helped me figure out how to activate it on my phone.
Highly recommended especially since wifi isn’t guaranteed or all that great.

Effortless and first rate from start to finish
Effortless and first rate from start to finish. Easy to install, top up, register, re-top whilst away. Simple to see your balance, useful reminders though not too many. Great prices, excellent connection speed and coverage. I was a bit worried about how I would cope out & about sightseeing in Japan needing to be constantly on Google maps but I needn't have worried. I'd give this 11 out of ten let alone 5 stars!!
