The best pocket wifi hands down
I go to Japan every summer and winter to visit family and I have always been renting pocket wifi off of rakuten. My family lives in a rural area of japan where the signal wasn’t very strong and wouldn’t connect half of the time. However, with the Diamond Buddy I had absolutely no issues and always had very strong connection 24/7. I will always use the Diamond WifiBuddy from now on!!!

Platinum WiFi
Worked great. But how do you know how much data you’ve used? Also, the battery consumption/ charging fluctuated dramatically at times. It would be helpful to provide the directions to optimally charge the unit.

WiFi works well, one of the units came uncharged
We liked the portable wifis and they worked well for the most part. Though, one of the units came uncharged and it was a hassle. Additionally, one of the portable batteries did not work/charge.
