Cellphone PrePaid T-Mobile?

Question

I have a regular unlocked cellphone.

If I go to America and buy a PrePaid T-Mobile SIM-CARD , can I enter it to my phone and use it? or I must own a T-Mobile Phone?

thanks

Answer 1

The phone will only work in the US if it is a tri-band or higher since mobile phones use a different frequency in the US.
