Very good product.  Works right after installation and activation.  Don't forget to turn on data roaming.  You may need to choose the mobile network manually.

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.

Used in Argentina and Brazil, along with my layover in Dubai. It worked well all around. When I had a trouble with the signal, customer service was great to help.
