Buying and activating the eSim was super easy. As soon as plane touched down, the eSim connected to a network automatically.

There were no problems at all! Everything worked super fast. I also shared the internet with my laptop—I watched TV shows and worked.

For my solo trip to Thailand, I chose to use the TrueMove 5G eSIM, and the overall experience was excellent. I received the eSIM QR code quickly after purchase, and simply scanned it according to the instructions to activate it. No need to change the physical SIM card, which is incredibly convenient for solo travelers. Customer service was also very responsive, providing immediate assistance with setup issues. In actual use, the signal was stable in urban areas, tourist attractions, and even while moving around, with smooth 5G/4G speeds. Navigation, map searches, and photo uploads all ran without problems. The 24-hour billing method was also flexible, ensuring no days were wasted. Overall, it's easy to use, has a stable signal, and offers excellent service, making it ideal for independent travelers.

I decided to try an e-SIM card for the first time. I read some bad reviews and bought this e-SIM as a backup. I installed this e-SIM for my wife and bought myself a EURO SIM card (five times more expensive). In fact, both worked well. I can't submit a review without rating the customer support. I'm giving it a 5, but I don't know how they work, so I haven't had to contact them.
