★★★★★ The setup was very easy, and I was able to use the internet immediately upon arrival. Using sightseeing and restaurant searches, as well as map apps, was very convenient. I had no complaints about the communication environment during my trip and am extremely satisfied.

I thought the SIM card would work on a cruise (directly at sea) from Shanghai to Korea, but I was wrong. The coverage was significantly better than a SIM card that only goes to Korea or only goes to China.

The connection was good, and since I installed it in advance, I was able to use it immediately upon arriving in Guam. I was assigned a local number, so I was able to make calls conveniently while there.

I disabled airplane mode before getting off the plane, and after connecting the SIM card, it connected smoothly after a short while. There were no complicated settings, and the signal strength was always stable, which was very helpful.
