Is there any company that uses SIM cards in the US?

I want to be able to use my telephone which I bought from outside of the US with a SIM card system from here??? Is there any way?

Is there any company that uses SIM cards in the US?
Cingular and T-Mobile





Sometimes AT%26amp;T depending on where you're at... I've had all three of them at different times within the last 10 years... T-Mobile has the best deals right now though, just got 3 RAZRs and one Samsung mp3 phone, with no money down, and $200 cash back... Unlimited mobile to mobile, and myfavs...





Pretty sweet deal.





To use your phone on a different network, you will have to unlock your phone, search your phone in google with the words unlock next to it.





Sprint and Verizon don't usually use SIM cards, only in certain cases, it will be difficult for you to find a place that will give you a SIM for either of those, i'd stick with Cingular or T-Mobile if you were going to do that though.





If you're planning on using your phone for that, you might as well sign up for a deal with a company that uses SIM cards, and get a free phone with them, then use your SIM card in your other phone, that way you'll have an extra free phone with the one you currently have.
