Reviews: Thailand 5G eSIM | Day Pass/Total Data Package | 1–30 Days | 24-Hour Billing | QR Code
Guest User2025-11-22
The experience of using a 5G eSIM in Thailand was truly fantastic. For this trip, I purchased an eSIM before departure, and the entire process—from receiving the QR code, installation, activation, to the actual network speed—was incredibly smooth and hassle-free. I received the QR code almost immediately after purchase; simply scanning it with my phone was enough for installation. There was no need to change to a physical SIM card or queue at the airport, saving a lot of time. Installation was simple; even first-time eSIM users could easily succeed. Upon arriving in Thailand, the network automatically connected as soon as I turned on my phone, with full signal strength immediately—very convenient. The network speed was surprisingly satisfactory. Whether in Bangkok hotels, shopping malls, restaurants, night markets, subway stations, or even in a moving Grab car, I maintained a high-speed and stable 5G network. Navigation, Google Maps, ride-hailing, checking travel information, uploading photos, watching videos, and even using ChatGPT for research were all incredibly smooth, with no disconnections or lag. Especially when taking photos and uploading them at the night market, the photos were uploaded instantly. Even my friends said my internet speed this time was much faster than when I went to Thailand before. The plan options are also very flexible. You can choose a daily plan or a data plan, with the number of days ranging from 1 to 30 days. I bought the 24-hour billing plan, which is very cost-effective. Unlike some telecom companies that calculate based on "calendar days," this one calculates the full day from the activation date, so there's no waste. It's very user-friendly for travelers with short stays or those using the service in segments, and the price is very reasonable. It's cheaper than buying a SIM card at the airport, but the quality is the same or even more stable. Customer service is also very responsive. I had a small question before installation, and they quickly provided a clear answer after I asked. Their friendly attitude made me feel very reassured. If you're not familiar with eSIM, the official website also provides clear illustrated tutorials, so you can succeed on your first try by following them. Overall, I give the user experience a perfect score. Whether it's convenience, network speed, stability, price, customer service quality, or plan flexibility, it's all highly recommended. Best of all, I didn't need to remove the SIM card after returning home, and it didn't affect my original phone number. The whole process was clean and efficient, and it's so much more convenient than a traditional SIM card. In summary, this Thai 5G eSIM is one of the best network products I've used during my recent trip. High-speed, stable connection, easy installation, and affordable price—it's an absolute must-have for travel. If you're traveling to Thailand, whether it's Bangkok, Chiang Mai, Pattaya, or Phuket, I highly recommend buying this eSIM. I will definitely buy it again on my next trip to Thailand and will definitely recommend it to my friends. Five stars without a doubt—it's a very trustworthy product!★

Reviews: Asia 9 Destinations 5G eSIM | Japan, Thailand, Vietnam, Indonesia, Korea & More | 1–30 Days | Instant QR
Guest User2025-09-02
This is my second purchase. The signal is strong even in Shangri-La, and I've been able to use it without any problems. I'm going to Kunming-Korea next, so if it works as well as last time, it will be perfect. It's very convenient to be able to use it in other countries without changing the settings. I'll definitely use it again.★
