Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

The signal is unstable. After watching videos for a while each day, the signal becomes extremely slow, and even mobile payment functions become unusable.

The network card provided by this adapter in Osaka demonstrated a very stable and fast signal, and was easy to install. It is also very reasonably priced.

Everything worked perfectly for us, the coverage was excellent, and our 3GB of data was more than enough for the day. I even shared the WiFi with my wife a few times. Even in a mountain village, we had stable 5G internet.

Since it's Tokyo, i expected there would be no problem at all with signal. Also visited Niigata for a day, and no problem either. I choose this docomo (actually iijmio) altho 4g, as a "just in case" backup of a different service provider, because i chose softbank 5g for my husband. Rates here in Trip are cheaper than in other platforms, so i always buy here

The SIM card is easy to use and set up. The signal is stable, although it occasionally drops to 4G and is a bit slow when traveling to the Biei area in Hokkaido, but overall it's okay. The price is reasonable and worth the money.
