Reviews: Thailand AIS 5G SIM Card | 35GB for 7days | Local Phone Number | Pick Up at Bangkok Airport
Guest User2025-12-25
I highly recommend buying it, everyone. This is my first time using AIS and I was amazed by its power. Normally, when I go to concerts in the hall, I lose my internet connection completely, or it's intermittent (more often than not), but with AIS it's very powerful, uploading photos and videos is smooth. If you go to Suvarnabhumi, buy a physical SIM card; the staff will set it up for you. Otherwise, you can buy an eSIM for convenience.★

Super convenient to have it ready when landing. It does what it says it will do. I would definitely trust this and use it again. The speed was good and installation was very easy. Just follow the instructions. The price here is much better than the other companies like aralo or roamless etc....★

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!
