No complaints

Pese a que mi compañía nacional de celulares se comprometió a desbloquear mi teléfono para poder usar la tarjeta, nunca lo hicieron, pero Japan Wireless me devolvió mi dinero aún habiendo enviado la tarjeta a tiempo y sin tener ninguna obligación, les estoy muy agradecida

I got this for one month and went various places with it, it has signal everywhere except for when a train goes through a tunnel or something like that, but even on the subway it has connection.
And I didn't have any issues in all my stay

I preordered a data SIM card and was able to pick it up at Narita airport after I had landed. Because I can't speak Japanese I can safely say that this SIM card saved my vacation, because I would never have been able to use Japan's public transport system without access to Google maps!

Worked like a dream, made traveling so much easier

it worked the whole vacation period without any issue. We traveled quite far and always had good coverage. In all good value and excellent service.

Easy to use and excellent prompt service sending the card to an residential address. Thank you for making my trip starting off right.

We purchased the 30 day data SIM card. It worked brilliantly. Certainly recommend this service.

I read a bunch of reviews for some of the more well known companies carrying pre-paid SIM cards but those places were charging a lot more than Japan Wireless. I'd give a 5 star rating if a key or paper clip was included (luckily I had packed a paper clip to open my iPhone). Internet speed was fast and reliable.

It worked perfect during the time. There were no surprises!
