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 used an eSIM in Thailand and it was very convenient. No need to change physical SIM card, just scan and activate. The connection was fast and stable in most places, including Bangkok and tourist areas. Internet speed was good for Google Maps, social media, and streaming. Setup was easy and only took a few minutes. Price is also reasonable compared to buying a local SIM. Overall, very worth it and hassle-free. I will use eSIM again for my next trip.

The SIM worked perfectly everywhere we went in Thailand, even in more remote areas. It also worked in major cities with 5G coverage.

I used this eSIM during my recent trip to Hong Kong, and the overall experience was excellent. Activation was very fast; I was online within minutes of scanning, which was very convenient as I didn't need to change SIM cards. Everything went smoothly; navigation and information searching were both very efficient. I will definitely repurchase it next time I travel abroad.

Very easy and simple to use. I chose a package, paid, and installed it. It took just a minute. Upon arrival, I enabled the selected eSIM and roaming. Very convenient.
