Yes in both cases the TM30 needs to be done again

I asked at Krung Thai Bank in Phuket and the woman who served me hadn't even heard of the Destination Thailand Visa. So I think it will take some time and will be accepted by some banks eventually. But nobody knows how long it will take. Since I do a language course with the Education Visa at the moment, it was possible to open a bank account at Krung Thai, I opened it just last week. Other banks like Krungsri, Kasikorn and Siam Commercial refused the Education Visa. Except Krung Thai, only the Government Savings Bank said they would accept the Educational Visa. With Krung Thai I had to choose a package with insurance though, which is 2,6k Baht per year but after the first year, it will be possible to change this package to the Standard Mastercard which is just 200 Baht per year.
