OMG! are you sure?? I just mailed the package today.
Bugger!
I am Scottish, been going to Thailand since 1993 and lived there properly for 5 years.
Thailand has one of, if not the highest rates of credit card fraud in the World and many sites will not accept credit card transactions from Thailand.
Unfortunately i know a lot of con men that live there (They are NOT friends just people i know) All of them are ex-pats. They use Pay Pal to rip people off. The fact that he asked for your sim card sends massive alarm bells off. You can buy a sim card from the 7- eleven there with out filling in any forms. I have loads of them lying about the house and it is very cheap to call international with them. Why would someone want an American sim card??
I know one guy that sold Millions, and i mean millions of £$£$£$£ worth of fake golf clubs through Ebay. He did get caught and is doing 7 years in a UK prison but he doesnt care as he will still have the money when he comes out.
He himself told me NEVER to get anything sent to Thailand or send stuff out of Thailand because the country is so corrupt that the chances of the item reaching you is pretty slim. And i include TNT etc in that. BUT things do get through, my mum sent me a birthday card last month, it did get to me but it had been steamed open to see if cash was in it, which there wasnt.
Its a bit late for you now and i am sorry i didnt see this earlier. Lets just hope everything goes smoothly for you.
