Great product and excellent service!
I had rented 2 Diamond Wifibuddy for my vacation and 2 weeks japan cruise. It worked very well but few days during the cruise, one of them stop working. I emailed them and they help solved the problem. Since then both of them were great products, above all they have excellent customer service.

We had no issues other than delivery wasn't at our hotel when we arrived but it did arrive later that same day. It worked perfectly and we were very impressed by the thorough communication.

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.
