The e-SIM is very easy to install using Curacode. I installed it beforehand, and when I arrived, I simply enabled it in the settings and everything worked. I have no complaints about the speed or quality of the service; everything was perfect. It's a great option for internet while traveling.

If you're traveling to Thailand, just get this True eSIM. Super convenient - no need to swap physical SIMs. Unlimited data, strong 5G signal even in islands. I used it for 5 days straight and it never lagged. Best eSIM for Thailand.

I booked this eSIM when I was stuck at Bangkok airport after my flight got cancelled. It was an easy and very convenient way to have constant, fast and stable internet access during my extended time in Thailand. Easy to install and even easier to use.

DTAC requires zero manual setup. All configurations are done by scanning the QR code. There were no network bugs throughout the whole trip, and I will repurchase it for my future visits to Thailand.
