Great Battery Life, Great Speeds, Great Reliability and Great Price!

Diamond WiFi Buddy will be my only choice everytime I visit Japan, had an amazing experience with it. Only lost service for about 5 minutes when I used it over the course of 8 days (14 Hours average usage per day)

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.
