Outstanding
We never lost service and the battery lasted about six hours before it needed recharging. We used it for 2 weeks and thought we got a great value. Thank you!

So helpful
Super easy to use and incredibly clutch! We loved the Diamond wifibuddy and never had connectivity issues. We had our own external charger that we used to keep running since we were out and about for the majority of every day and it worked like a charm. We'll be looking for these in every country we travel now.

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.
