I just arrive Bangkok and I need a micro Sim for my new Iphone 4.

I need a micro Sim card thats cheap to call inside Thailand and overseas (Europe), and you can easely get refill card. I will also use it on Internet.

Any suggestions, what provider and card to get?

What do you guys use?

Thanks

You can buy a Pre Pay Hi-Speed Micro SIM. If not available, you can buy a standard Inter SIM for 49 baht from any 7/11 or Family Mart and then take it to a phone shop to have it cut down.
