Do I need a Thai ID number to get a SIM card as a DTV visa holder in Thailand?

All 3 cellular carriers have booths at BKK. There is no price difference between company stores and independent resellers (7-11) as all the available plans are published.

Go to any booth after you clear immigration and hand the attendant your phone. They will have you choose a plan from the chart. Show your passport. They will load and test your phone to ensure it works.

This is not difficult.

Most will use an eSIM.

Some will add the Thai SIM to their existing as a second SIM and toggle back and forth using the phone’s settings screen.

I would never trust a 7-Eleven clerk to load a Sim into my phone however, the people that work in the airport can do it blindfolded, all day long every day.

Go to AIS shop with passport for long term plan if stay here for long time.

Monthly plan as low as 500B per month.

Only need passport if you buy in shop.

Get a Saily eSIM

I recommend to get a sim from 7-11 and you dont need to change the number often like that .. they wont ask the id card from foreigners

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

Get a sim from a 7-11 or phone shop and pay between 200 and 350 Baht for your 30 day plan of choice (data, calls & texts) then renew every 30 days. You keep the sim not change it every 30 days.
