Highly recommended to get when you travel to Bangkok or other parts of Thailand. Cheap, strong connection to use.

It works great; I had internet access right upon arrival. Activation was very simple. The network was good throughout almost all of Pattaya.

I bought an e-SIM and activated it right away. I have a good 5G signal in central Pattaya. The good thing is that it's not a daily package, but an unlimited one (I think the description says 50GB, but I haven't checked, so I don't need that much).

This was my first time using an eSIM card. I liked it: it was easy to register and activate on my phone. I got it for 13 days and used it in Thailand, sharing internet with a second phone. The signal was good, and everything loaded quickly. I used local messaging apps to order food and groceries. I also used Russian messaging apps for video calls home.

I went to Vietnam → Cambodia on a woman's solo trip and stayed in Cambodia for 9 nights (Phnom Penh 2 nights, Krache 1 night, Siem Reap 6 nights) ♪ Thanks to this eSIM, it was a fulfilling trip ^ ^ Use again Shu!

Best connection, did not have any problems with it even when we went island hopping. Was connected the whole time. Though would advise one to do the authentication before flying put as it can be a bit complicated.
