Reviews: Thailand AIS 5G SIM Card | 15GB 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.

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.

An excellent eSIM for a vacation in Thailand. I used the eSIM in Thailand for 10 days—the connection was stable and fast. Internet connection was available immediately after activation, without any unnecessary settings. It's easy to use navigation, order a taxi, chat on messengers, and share photos. No need to search for a local SIM card—everything is simple and convenient. I'm very happy with it; it's a great option for traveling around Thailand.

We bought an eSIM before our trip to Thailand and couldn't be happier! We activated the service in advance, arrived at Phuket airport, and the internet was working right away, without any delays or hassle. Reliable connection everywhere. Now we can use the internet all over the island without any problems: at the hotel, on the beach, on public transport—the speed is stable, the coverage is excellent. Even in remote areas, the signal is reliable, which is ideal for a family with a child. A bonus—we also received a local number and a Thai mobile number, so we can sometimes call each other without extra charges—it's convenient and affordable. Of course, the internet is what we mostly use: maps, chats, video—everything works. We recommend eSIM to all tourists in Thailand!

The network is still working great after I recharged it. I haven't run into any issues at all. I've tested it, and this esim can be used long-term. It's totally fine!
