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。

3 years contract you only can join one tele dealer, warp yourself
like hell, if others go down the price with a killing plan, how can you
switch?? one cell phone in your hand with a best price and without longer
contract, you can swith the plan anytime you want, the point is if you
can have a great deal of Chinese cell phone.

我用国内带来的手机。
优点：有中文，电话簿什么的，方便；如果想换公司，也很容易，手机没有锁；而且，现在好多都是4频手机，所以拿过来就用，没有任何问题；另外，时尚。
缺点：在中国的各种保修都用不上，一旦有问题，就很麻烦，这边的公司也不管；有些下载是针对手机型号的，在中国卖的手机，比如在fido，想下载东西，找不到对应的手机型号。

那你用的是预付卡，那肯定没有计划的合适啊．．．

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。

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.
