Simple and easy. Unlimited data and you have a number which makes it easy to contact thai numbers without having to use data roaming. This is my go to and reasonably price
Numbers needed to retrieve voicemails don’t work, automated messages and texts are in Thai only even though I selected English as my language.
It was supposed to be a dtac number but it was True, not allowing me then to use my app and credit saved into the app, etc
