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.

I traveled to Tokyo in March 2026, landed at Narita airport. In side Narita airport, signal was weak and slow, after came out of the building signal got slightly better. So, don't expect too much when you are in that area. In Tokyo area, internet speed was good, usable in Subway even while riding the train. I tested internet speed, in most places would be around 50-160 Mbps, but when you are underground it would drop to approximately  30-60 Mbps. I departed Tokyo at Haneda airport, I would say signal inside Haneda airport is much better than Narita. Overall service is good for the price I paid  ~ $10 for 5 days. < Device - iPhone 13>

I used it in Osaka, and it worked almost perfectly, but the subway would slow down sometimes. Does anyone know of anyone who lives in the mountains? I stayed there for a day, and it didn't work that well that time either. But overall, it worked well! Highly recommended!!! I'll be using it again when I travel next month.

It worked and was activated in China with roaming. TG works perfectly. Further, in the Philippines, there were no problems.
