Especially if You're on the younger side, and you don't have any serious health conditions, in my opinion, you don't need full medical cover, look into a good accident insurance policy, and also a good critical illness policy, because if the worst should happen, that is what will cost the most money, most other minor conditions you could probably just pay for it yourself, medical treatment in Thai government hospitals isn't stupidly expensive, for example a decent accident insurance policy is between ฿6500-฿8500 roughly, AXA and AIA are good, also as previously mentioned Pacific cross should have a policy that suits your needs.
I've seen Thai people living on ฿15k in issan villages, while farangs need much more money to live comfortably, and seem to suggest anything from ฿40k to over ฿100k a month, so what you would spend is anyone's guess 🤔
he said he is on an O-A visa, if I'm not mistaken, you can get 2 years out of that visa, with 1 border bounce, and then you need to do an extension of stay, it's not like he is bouncing in and out regularly for free stamps.
every time someone asks for advice about opening a bank account, you pop up, saying it's impossible!! when it is 100% possible, when you get the assistance of an agent, there are agents in Pattaya that open bank accounts everyday, for people on short term visas, so your advice saying it's impossible is incorrect.
฿7000 what does that include?? Lots of agents in Pattaya do it for ฿3500-฿4000, without buying the banks accident insurance, you just need to also pay the bank for the ATM card, and make a deposit into your newly opened account.
