I use a Skype subscription (have done for many years). For USD $20 per month, I can call almost any phone (both landlines and mobile) on the planet. As an expat who also travels often, this has been an excellent investment.
PS - Bloody hell, you jinxed me! I just received an e-mail from Microsoft, to advise me that Skype is retiring in April.
Sorry, I should have been clearer. I’m referring to people who are staying for their second 180 days, who already stayed the full 180 days previously. I will edit my post.
That would be a nice 18 day road trip. I have enjoyed several 1 to 2 month road trips around Thailand, and it’s a great way to experience the countryside (in fact my next trip in Jan-Feb will be in the south). If you don’t already have it, download the Booking dot com app for excellent accommodation choices. Happy trails.
