Reviews: Thailand AIS 5G SIM Card | 35GB for 7days | Local Phone Number | Pick Up at Bangkok Airport
Guest User2026-01-21
It's convenient because you can find it right after exiting the departure hall. The staff was friendly and set it up quickly. The signal was decent, and I used it well. However, I was a little worried because my plan was suspended after 35GB, which was a bit of a concern. I was satisfied because the price was cheaper than buying unlimited data on-site.

I bought an eSIM when I was back home. I activated it via airport Wi-Fi upon arrival. It works as a data hotspot, and so far it's worked everywhere we've been. Reception is a little worse at the hotel, but it doesn't affect data usage.

Great deal!! Very useful. It can be a little confusing to install at first due to some unclear information about the eSIM number, but Trip.com support was very quick to help me resolve it.
