As the title suggests, we were very happy with the SIM cards.

Good servce at a competitive price

Great option! Ordered if for my boyfriend who uses android not compatible with e sim. I had it shipped to my hotel and was there when I checked in. Very easy set up with instructions

I've been very happy with the 30 day sim.
Worked 99% of the time even in most subway stations.
The only critique I can give is that installation for first time users can be very confusing, luckily I had help from a more experienced person who could help me.

Great experience, easy to get

They delivered the SIM card to my hotel on time. Easy to install and works perfectly!

I bought this 30 days sim for a month long trip in Hokkaido. Service was great in the mountainous areas! would definitely buy this again

Really happy with my sim, we have spent 3 weeks traveling around Japan and the internet on my phone worked perfectly everywhere! Definitely recommend people use this as it is very reliable!

A solid internet connection across Japan, easy to set up, much cheaper than survives, and available to pick up at the airport. Highly recommended.

After the initial configuration the SIM didn't work, but I contacted Japan Wireless support team and they provided immediately the solution. After that, the SIM worked great!
