Lifesaver during our travels
We ordered two since we were a group of 5. Visiting temples and shrines during the busy New Year season, they were invaluable for keeping track of where everyone was. Good signal and pretty strong battery life kept us connected pretty much all day. We often got better signal and faster speed than hotel WiFi.

Diamond Package
The wifi was fast and reliable. However I wish a larger battery pack was given since the one used didn't last the whole day.

Quick Setup Guide

Specifications
  • Requires a SIM Unlocked device with esim capability. If your device is locked, please contact your carrier to unlock it.
  • We include thorough instructions, via email, through our website and with customer service.
  • These are data-only SIM Cards. Carrier-based voice calls and text messaging are NOT supported. However, data-based messaging and telephony solutions such as Skype, Facetime, Whatsapp, Line etc. are supported.
  • To avoid provider validation complications, in some cases when users order far ahead of their actual trip, we will send a confirmation email, with a separate QR code later on, closer to the departure date.
