I had purchased other types of SIM cards before where they would throttle your speed if you used too much data in one day, this SIM had no throttling at all, and I could use all my data in one day if I wanted to.

Worked perfectly, with good speeds and solid connectivity

This a very sneaky card that deliberately doesn't advertise the fact that they slow down speed just after 100MB/day limit

Worked great, fast speed, once I got it going, it was perfect and provided a much-needed tool and lifeline in Japan since I don't speak the language

It worked right away and gave pretty fast speeds every where I wen in Tokyo and beyond.

Good service, decent speeds, good coverage.

What happens if I use up 100 MB in a day for 100MB/day SIM?The speed will be slowed down to 128 kbps until the next day but you can purchase another 100 MB using our Refill 100 function through our App to get the speed back up.

Speed was good, I was able to watch a few videos during down time while waiting for trains, etc.

Quite dishonestly it says "Reliable speed" on all its advertising

Overall, fast speeds in the locations I travelled to: Tokyo, Kyoto, and Hakone.

Has excellent reception and speed in most areas, urban or rural

As far as speed goes, they were on par with what you'd expect on many carriers, and not once did I had slow speeds or dropped connection, it was quite reliable all the time
