It worked well enough and connected right away once landed, didn’t have to contact support, instructions were pretty clear. Hope it doesn’t count towards my days as I installed it from the app and then it started activating but not sure if it activated properly as I was still in Canada.

This is my second purchase. The signal is strong even in Shangri-La, and I've been able to use it without any problems. I'm going to Kunming-Korea next, so if it works as well as last time, it will be perfect. It's very convenient to be able to use it in other countries without changing the settings. I'll definitely use it again.

I always use it when I come back to Japan during my trip around the world. It's easy to connect to the internet, so I can use mobile payments like Mobile Suica and Rakuten Pay.
