Reviews: Thailand 5G eSIM | TikTok & ChatGPT Available | In-App Installation | Day Pass/Total Data Package | 24-Hour Billing | QR Code
Guest User2025-12-19
Excellent eSIM. I got two, one for me and one for my office, for 25 days with GB per day, for about 730 rubles each, I don't remember the exact price. They activated it upon arrival in Thailand, everything is fine, the internet is fine. I recommend it.★

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.★

Reviews: Thailand true dtac 5G eSIM | Total Data Package/Unlimited Data | 5–30 Days | 24-Hour Billing | QR Code
Guest User2025-12-19
I'd previously rented pocket Wi-Fi, but this was my first time trying eSIM. I was very nervous before I left about whether I would be able to set it up, but I'm very happy with the results!
What was particularly helpful was the customer support. I emailed them about my concerns before going to Thailand, and they carefully explained how to set up my iPhone with images, which helped me get it working smoothly after arriving without any trouble.
As for the communication environment, thanks to the True/dtac 5G line, the speed was fast even in Bangkok and Pattaya, and I was able to use it comfortably without a single dropout. I no longer need to carry around a heavy pocket Wi-Fi, so this and eSIM will likely be my only choice for future trips to Thailand and overseas!★

Reviews: Thailand AIS 5G eSIM | Total 30GB/35GB | Local Phone Number | Real-Name Authentication Required | QR code
Guest User2025-12-19
The Thailand AIS eSIM worked perfectly throughout my trip. The mobile data was very reliable, with fast and stable connection in cities and tourist areas.
The installation process was quick and very easy, and I was connected within minutes. It’s also very cheap compared to other options, making it an excellent choice for travelers. On top of that, the free travel insurance and included vouchers were a great bonus and added extra value to the booking.
Highly recommended for anyone traveling to Thailand who wants affordable, dependable, and hassle-free mobile data!★

The internet worked perfectly the whole time, plus they gave me a phone number, which I registered with Lazada to place an order. I recommend it.
