90 day reporting is just that... a report to immigration on where you are and has nothing to do with your visa. It is not an extension nor an approval to stay.
You still need to follow the DTV visa rules in addition to the updates on location (90 day report). You're choices are to leave before 180 days or file for an extension.
For most people, leaving Thailand for a short trip or border bounce is much easier than getting an extension
After you do a border run and return them the 90 day clock restarts
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.
