I have a prepaid from True. Minimal service, just for OTP. 120 thb a year and 49 thb for the SIM. Use Google Fi unlimited for my world wide cell service and data.
The days of getting in multiple times a year on visa exempt are coming to an end. It's all at the discretion of the IO. You might get lucky, might not.
you do the Non O online while out of Thailand ( like the DTV ). It should take about 10 minutes to apply if you have the information together. You can only upload one file for each required document, so you need to get all the bank statements into one document. That gives you 90 days in Thailand.
Once in Thailand you can apply for a 1 year extension ( this is the retirement visa )
Do not apply for the Non OA. Apply for the Non O, it has less requirements. Look on YouTube there are videos on exactly how the process works and how to fill out the online application. It's very straight forward.
simple answer.... You are completely wrong. I simply don't want to go to immigration. I had a successful career and I would rather throw money at problems than do things I didn't want to do.
Just because you choose to do something doesn't mean that those of us who don't are morons. Enjoy standing in line at immigration, I'll be out riding in the mountains....
