Guam WiFi was born in response to customer requests.
This is a completely unlimited 4G plan, so you can use the internet without worrying about data usage during your stay in Guam.

Even though there are a relatively large number of free WiFi spots in Guam, if you are concerned about security, or if you are using Google Maps instead of a car navigation system in a rental car, having unlimited WiFi will allow you to use the Internet with peace of mind, just like using a smartphone in Japan.

Guam, which is only a 3.5 hour flight from Japan, is popular with families and friends. Enjoy a stress-free trip to Guam.
