Great way to stay connected to wifi in Japan
My only complaint is that the device itself had a short battery life, but the extra battery that was included was helpful

Everything received and worked as
Everything received and worked as expected. Battery life for the pocket WiFi was a little disappointing as some days I got as little as 4 hours before having to plug in to a backup battery.

30 days diamond pocket Wi-Fi
It was a nice experience, I had good signal and speeds almost all the time. The only thing that could have been better is the devices battery, sometimes it would show as charged and after 30 mins it would run out of battery. But since I had a power bank it was fine.

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.
