The eSIM application process was quick and easy! Convenient automatic installation immediately after purchase, and it worked flawlessly! The internet is very fast, unlike most hotel Wi-Fi. I purchased two passes, for 10 and 7 days. It's a great solution for short trips around Thailand.★

I still haven't been able to connect this SIM card. I think it's my own fault. I have a hard time using all these modern gadgets. I didn't think to contact customer support. And my colleagues couldn't handle it either.★
