Fast
Faster data speed than I would have expected. It was much faster than all the five star hotels I stayed in.

Awesome device, awesome service
The diamond wifi is fast, small, and more than capable to handle wifi needs for a small group. The data allowance is really generous before any kind of throttling happens, it was fast from beginning to end. Highly recommend.

Fantastic device and service!
I have T-Mobile, so I got 2G data and texts; SO has Verizon, so none of that. This was a life saver on many occasions, mostly just for finding out where we were! Instructions were clear and helpful, extra battery is a nice bonus (we also brought our own for our devices), and while we didn't use the pouches provided regularly, also a nice bonus!

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.
