This isn't something related to the DTV specifically, it is a requirement for anyone (except a few special visas) that stays in Thailand for 90 days.

Every 90 days foreigners need to file a report with immigration of their address.

I keep two numbers

1) Easy to get a prepaid monthly plan from AIS or other providers. Thai number and data. Set this as your primary number and data. Get ESIM installed at the store. I pay 399 baht per month for 100gb

2) keep home country number in secondary position. Very beneficial for banking, etc in home country.

Nomad version of dtv. Flew out and back twice. Also one land border crossing. No questions for me but I've heard others have had questions when entering again.

@Kevin *******

ok, maybe so. How many is it?

Maybe next time, I should list every simgle possible scenario and possibility that could possibly happen....

I shared the basic overall concept. Sorry if that doesn't fit what you like.

@Kevin *******

possibly, this is a good point, but this has not happened yet for people entering through immigration. And totally agree for those that do extensions

I'm not sure what you mean by "activate it" but the 5 year visa validity starts on the day you were approved.

Then each time you enter Thailand you receive a 180 day entry stamp.

Come and go as often as you like during the 5 years. Each time you receive 180 day entry stamp.

Edit: of course any and every entry is up to the immigration officer and depending on your specific circumstances, the port of entry, which type of DTV, the mood of the IO, and many other factors, entrance is never guaranteed for ANY visa including the DTV.

I have entered and exited a couple times already on the DTV (remote work nomad). Never had any questions from immigration. I went to Taiwan, Spain and Laos.

I definitely prefer airport immigration over the land border at Vientiane because much easier than the walking, crowded bus between Lao and Thai border, etc

The other country didn't ask any questions related to the stay in Thailand or DTV. Irrelevant to them

It sounds like you possibly have a misunderstanding of the DTV...

The 5 year clock has already started on your DTV from the day it was issued. When you enter Thailand for the first time is irrelevant for this.

You can enter Thailand as many times as you want during the 5 year validity.

Each time you enter, you receive a 180 day entry stamp. You can enter as many times as you want.

And finally, you can not have multiple visas at once. Now that you have the DTV, then this is what is used when you enter Thailand

Customers are Thai. Not allowed as a remote worker. Need a work permit to do this

Come and go as often as you want during the 5 years and get a 180 day stamp each time.
