The only possibility for an issue is at initial check when you're departing but even that is unlikely since you have a return flight booked. They should be aware of the 30 day extension option or multiple other options available (exit/reenter Thailand to other countries as part of your trip). Almost zero chance of a problem but in the ,000 chance, the onward ticket sites offer temp tickets for $20-$25. I'd bet no problems tho.

This is true for US expats that move to Thailand (or anywhere outside the US).

To avoid it, use a residential address of family/friend and do not mention it.

Agreed AIS. Prepaid plans are cheap and offered for tourists but if you are going to live there, they offer even cheaper post-pay plans that are great. You just need to show them proof of a long term visa (ex. retirement visa) and you pay monthly.

PH is beautiful but unless you live there on a 12 month lease, it's much more expensive to visit for a few weeks. The food is terrible.

@Ian ********

Been there. Stayed in Cebu for over 2 weeks, few days in Manila and surrounding area. Accommodation costs were about 3-4x higher than in Thailand for poorer quality accommodations.

I think this is referring to 'living costs' meaning a 12 month rental lease option. For travelers who visit for a few weeks, the cost for accomodations are much higher than in Thailand and you get poorer quality in PH for that higher price.

@Reggie ******

Assuming you're eligible for the current 60 days exempt, then you can easily extend that an additional 30 days in Thailand.

Ok but I disagree. IP numbers can be detected with modern fraud prevention technology. A cellular# becomes an IP phone# after it's ported, hence it is then treated as an IP phone#. Also, some 2FA systems will happily accept the number that's configured but the text or phone call may never be successfully received.

Main advice - no need to port THEN test. Just create a Gvoice# and test what's needed beforehand. Superfluous info - I've used Gvoice since it's inception (15-20+ yrs?). I lived in Thailand . I access too many things to recall which had a problem but from experience, I no longer rely 100% on my Gvoice for success with all 2FA. Easy to set up and test everything in advance. The actual # doesn't matter, it's whether that company detects that it's an IP# and/or allows that type of #.

@Tony *********

IP phone numbers (ex. Google Voice) are hit and miss. Some institutions work, some don't. Don't setup 2FA then port to Gvoice. Test 2FA using Gvoice on everything you need it for.
