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 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.

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 esim was really good, the signal was always strong everywhere I went to, some places are pretty high and far away like Togakushi Shrine, Shibu onsen … but I never had any problem with the signal, I bought 2 sim cards, 1 is unlimited and the other is 2gb/day but I felt like I never ran out of data even with the 2gb one haha
