Guest User2026-01-03
Great experience with e-SIM in Thailand!
We got a 3GB per day plan for two weeks—it was enough for navigation, communication, and social media. The connection was stable everywhere we went: we never encountered any interruptions or lost signal.
Installation took just a couple of minutes—we followed the instructions, and everything worked right the first time.
I recommend it: convenient, reliable, and hassle-free!★

Upon arrival in Thailand, the eSIM was activated smoothly, and I was able to access the internet immediately! AIS's 5G network speed is incredibly fast. Whether it's checking maps, sharing photos, or occasionally watching a video, everything is super stable and smooth, allowing me to stay connected with family and friends anytime and get real-time travel information, greatly enhancing my travel experience!★
