那款手机能带到美国用?

I got my Samsung phone for free on Amaze.com and signed a contract for 2 years with AT&T.
And if your phone support 1800 HZ, you can insert the US SIM card in your cellphone.
But you still have to pay for the plan.
So I suggest you leave your phone to your family and get a free phone with plan in US.
It is said sait AT&T sevice is better than Sprint.
And Verizon is not bad too.

都没用。美国的电信公司每家公司手机都不同制式。而且都是随服务合同送手机。

只要是三频手机理论上都可以。
不过你只能选择少数公司的服务，比如T-Mobile...他们还提供prepaid那种sim卡...

像是Cingular, Verizon, Sprint之类的 貌似是都不提供那种服务了...

建议不要带了。毕竟你买一个plan就会有免费手机。
