从价格、入网方便度、使用预付卡、保修和中文显示各方面的优劣。
但是听说国内三频手机在美国某些地方不能使用。

这里的手机拿回国是否100块人民币就可以UNLOCK？
但是UNLOCK之后拿回来还可以正常入网和享受保修吗？

在这里就可以unlock你的手机，有些厂家的手机，如Nokia，可以免费Unlock，这个网上有热心的朋友提供解锁方法，你可以自己耐心找一下，前面的帖子。

Not only locked, but also frequency. Even you buy the phone in Canada.

三频手机is 900/1800/1900, 1900 MHz is used most in North America, but 在美国某些地方不能使用, because of 850 used, same as 900 in China, came from 10 years ago for the analog system.
Quad-bands phone is international, best to buy.

我觉得诺机亚的手机挺好的，我就从国带来的

肯定是从国内带 ，这得电话你不能换别的电话公司，太滥 。不值得考虑。
