will restrict your purchase of a GSM phone or CDMA phone.
GSM phone has SIM card, CDMA phone doesn't have SIM card.
AT&T phone is GSM phone, Sprint phone is CDMA phone.
中国电信采用CDMA机卡分离技术, 全世界其他地方的CDMA都是机卡一体的，你买回去没
地方插中国电信的卡。Iphone 5以上好像可以，没有研究过。So if they use 中国电
信, the CDMA phone from USA most likely won't work.
中国移动and中国联通seems use GSM phone, if that's the case, you can buy an
unlocked AT&T 三星智能手机. It has to be UNLOCKED!
Hope I'm not confusing u :) |
