I paid for the card in advance and activated it upon arrival in Thailand. Everything worked well, and the connection was stable.

Went from an eSIM through Verizon to this and wish I would’ve have gone with this from the start. Cheap and reliable, no notes

Buying a virtual card is easy. Installing it was a bit confusing at first. We received a few. Just enable roaming on the virtual card and it's up and running. It works well everywhere, even on the subway. 5G. I highly recommend it.
