Worked under 3 minutes or so. Had to select a different APN and select the network manually. Great speed afterwards!

Just got the Jetpac eSIM for Thailand. The installation was quick. As an Android user, I had to type in the APN settings manually. The eSIM wouldn't connect automatically to the correct network, so I manually connected and restarted the phone. Upon rebooting the device, I got 5 G from DTAC right away. Overall setup took 3 minutes, and the speed is fast.

We (4 people) all used Holafly's eSIM - on both Android and iOS devices. None of us had any problems and the network coverage was consistently good. We traveled with it in Bangkok and Krabi.
