I used around 9GB out of the 20GB over 12 days, almost 2 weeks, since I had it on every time I went out and it was absolutely worth it~ Activation was super easy, and the instructions were clear and straightforward. The connection stayed strong and consistent throughout the entire trip, and I didn’t experience any signal issues at all, even in very crowded areas like Silom during Songkran! I also love that it supports hotspot sharing~ I’ll definitely avail this eSIM again on my next trip to Thailand 💕

It was really convenient to use, the instructions are a little handful but when you get around it you can start enjoying your data. This is a hack for saving while getting the value of what you’re paying for :) Thailand is a 10/10

Having an e-sim is really helpful especially when you are in a foreign country because roaming services can be quite costly. I had no issues from setting up to using the unlimited data. I will definitely use this e-sim again.

Used the Klook 5G eSIM (AIS) during my recent trip to Thailand and it worked really well for me. Setup was easy—just scanned the QR code and I was connected as soon as I landed. The signal was strong in Bangkok and other tourist areas, and the data speed was fast enough for maps, ride-hailing apps, and uploading photos. Super convenient since I didn’t have to line up at the airport to buy a SIM. Overall, a reliable and hassle-free option if you want instant internet when traveling in Thailand.
