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.

Reviews: Thailand | 5G eSIM | Day Pass/Total Package | 24H Billing | 1-30 days | QR code
Guest User2026-02-25
Installation was completed with just one touch of the app, and upon arriving at the airport, I switched to the eSIM and roamed on. The signal was perfectly fine in Bangkok and Ayutthaya. I purchased a 1-day 3G plan, but if I use the hotel's Wi-Fi as well, I might be able to get by with less data. 🤭 In any case, I'd definitely like to use it again next time.

I bought two 50GB SIM cards for 10 days. 5G internet works flawlessly everywhere in Pattaya, with strong reception. Video calls, YouTube, and TikTok were all a breeze. Activated upon arrival. Convenient and fast. I recommend it.

Reviews: Thailand AIS 5G eSIM | Total 30GB/35GB | Local Phone Number | Real-Name Authentication Required | QR code
Guest User2026-02-21
Best connection, did not have any problems with it even when we went island hopping. Was connected the whole time. Though would advise one to do the authentication before flying put as it can be a bit complicated.
