I used it on my iPhone. One-click installation completed the day before departure, making preparations a breeze. Activation at Suvarnabhumi Airport was also quick. There are many activation instructions available online, so I printed out some that looked useful and brought them with me to follow along just in case. The connection was excellent in Chiang Mai's Old Town. While connection was a little difficult as I left the Old Town, it was smooth once I arrived at the tourist spots up in the mountains. When traveling from Thailand to Cambodia, the connection was automatic, so no setup was required. Siem Reap city was fine. Connection was somewhat difficult around and along the way to the ruins, such as Angkor Wat. While LINE messages were sent after moving locations, I had to resend images several times. It might be a bit stressful when sightseeing on my own while looking at a map. Overall, the connection was stable, so I'd definitely like to use it again next time.
