The 5G connection is simply excellent. We activated it in Russia, and as soon as we arrived in Thailand, everything was flying; 2GB was enough for everything.

Excellent connection, connected without any problems. And there was a bonus: more days and unlimited internet. For the price, it's simply amazing!

Our main location was Patong. We also took trips to the islands. The card worked flawlessly everywhere. Sometimes the internet speed dropped a little, but nothing critical. I bought two cards, one for me and one for my wife, with 20GB each. We didn't use up even half the data in 12 days. We didn't have to limit ourselves in any way.

Everything was very fast and cheap; I couldn't find anything cheaper. 5G coverage was everywhere, and the internet was very fast and stable.

I used an e-SIM for the first time. I installed it using a QR code in my home country, and internet was automatically available in Thailand. There were some minor issues, but customer support quickly helped me out!

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.
