Sorry to interrupt. I also have some problems calling to Thailand, from Singapore. The number I have is 09-240-XXXX. (Mobile number) I dialed, 021-66-9-240-XXXX. (021 is the IDD operator that I used in my country). Alternatively, +66-9-240-XXXX Everytime when I called, I always got to hear "Borigan... ton rab.... Welcome to the call back centre....", is the user not using his/her phone (switched off or no network coverage), or whether I dialed correctly? Khob khun mak~
