A great way to stay connected at a low cost. Everything is very clear from purchase to installation. I recommend it.

Guest User2025-08-25

Bangkok and Phuket sibeh crowded, sometimes the Wi-Fi will spin like sotong kena goreng. But if go ulu places with fewer people, the connection damn fast one.

Guest User2025-11-28

Convenient. Right at the airport upon arrival in Bangkok, I connected to the free Wi-Fi and entered a screenshot of the QR code into the app. Thai text messages started pouring in, and within minutes, the internet was back up.

Guest User2025-11-28

I’ve been buying different eSIMs for my regular trips but I’ve to say that this particular one was the best out of all. Full 5G signals all the time and enough data. Very reasonable price. I have to save it for my future trips. Amazing eSIM with AIS network.

★

Guest User2025-11-29

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.

★

Guest User2025-07-27

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!
