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

Geland in Tokio, vliegtuigmodus uit en ik was online voordat ik bij de paspoortcontrole stond. Geen rij voor een simkaart en achteraf geen verrassing op de rekening.
