Reviews
My husband and I used it, and it was easy to set up, with clear and easy-to-follow instructions. We also had fast internet everywhere we went in Bangkok. We didn't have any signal problems.
This esim is really helpful while touring around Bangkok and Pattaya. Great purchase for my 5 days trip.
I used an eSIM during my trip to Thailand and it worked perfectly. Setup was fast, the connection was strong, and I had reliable data throughout Bangkok and other cities. No need to swap SIM cards — super convenient for travelers. Highly recommend!

very convinient to use. hassle free, all the instructions that you need are provided in an instant and it is very easy to understand. didn’t have any problems using this. I got the coverage that I need and did non experience any downtime.
I was initially worried about network issues, but I was surprised that it worked immediately after purchase. The 5G speed is very fast, comparable to 5G in China. Very good and the price isn't expensive. The key is that the eSIM is convenient, no need to remove and install physical SIM cards.
