You go to the true shop with your passport. And you get your sim you can’t buy it online as you need to verify yourself for a SIM card that only works with Thai id
You can also get a card from Finn mobile they are cheap and have good service have them for years as my 2 sim
and still all of the 3 are tourist visa 😁 non of the 3 open you the route for PR requirements. Believe me I’m shocked how often I need to show my WP to get a simple service. The struggle with that on a TR going to be annoying as hell
it’s still not a resident visa. If op wants to be an immigrant not a tourist. He/ she should get the immigrant visa 😁 a lot of people report you can’t even open a Bank account on it without agents help
Pretty easy if you want to live in Thailand you get the long term visa that’s available at that time. The DTV was pitched as a workcation never as an immigrant visa
