Coming to Japan alone is comfortable. No need to worry about communication. The signal is good, no cuts. Plus, you can watch many series. Calling the hotel, the signal is good. It's very good. Normally, I use roaming, so the internet runs out very quickly.

I purchased a data plan and it worked perfectly. The connection was fast and stable throughout my trip, even in more remote areas. Activation was quick and easy, and the price was very reasonable. I’d definitely buy it again next time.

Good to be connected at all times. Better to pair it with a VPN since the IP address is in Poland. Otherwise very good product
