I used Viasimo to travel home to California this year. The instructions were super easy to follow and I had no problems with the service for the whole 20 days that I used it. It was nice not to worry about

Landed in Tokyo, switched off flight mode and I was online before I reached passport control. No SIM-card queues, no surprise bill afterwards.
