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 excellent and fairly fast in Tokyo and other areas of Japan, and the price is very affordable. Highly recommended.

The signal was quite good in Osaka, rarely dropping both in the city and outside (Kyoto, Nara, Uchi, Biwago). The signal was excellent at USJ, with no lag. There was some occasional slowness while on the train. Updating social media was fast, and I rarely experienced any stuttering. There were a few brief delays, but the signal quickly returned to normal.
