最全手机术语
一、与运营商相关的术语1、GSMGSM是全球移动通信系统（GLOBAL SYSTEM OF MOBILE）的缩写，它是由欧洲电信标准化协会（ETST）制定的一种数字移动电话系统标准。
2、CDMACDMA是Code Division Multiple Access的缩写，即码分多址。
它是根据美国标准（IS－95）设计的频率在900－1800MHZ范围的数字移动电话系统。
CDMA系统抗干扰能力强、系统容量大、接通率高、噪声小、发射功率小的新型数字网，能实现移动电话的各种智能业务。
3、SIM卡SIM卡是Subscriber Identity Modle（用户识别模块）的简写，它是存储用户的签约信息的，PIN 是SIM卡的密码。
4、PINPIN是Personal Identity Number的缩写，意为个人用户识别码，是为防止手机被盗用而设定的密码，有4位数组成，初始值是1234，用户可以按照手机说明书操作更改。
如果连续三次输入错误的PIN码，SIM卡将被锁住。
PIN码有PIN1和PIN2码两种，PIN1就是SIM卡的个人识别密码。
PIN2是设定手机计费时使用的。
如果输入三次错误，需要用PUK2码解锁。
PIN2、PUK2这两种密码与网络计费及SIM卡内部资料的修改有关，所以不会公开，而且即便PIN2密码锁死，也不会影响手机的正常使用。
因此，PIN2码和PUK2码不必去刻意理会。
5、PUK解锁码（PUK）是SIM卡的解锁码。
从技术上将，当用户的SIM卡被锁住后，用户应输入SIM 卡解锁码（PUK码），输入正确，SIM卡的锁才能打开。
如果输入10次错误的PUK码，SIM 卡将自动报废。
如果用户不慎把SIM卡锁住了，有两种方法解决：1）立即关掉手机电源，不再对手机做任何操作，然后带手机与SIM卡以及购机凭证到运营商的营业厅去请技术人员解锁。
2）致电运营商的服务热线，在经过简单的用户资料核对后，即可获取PUK码，解开手机锁。
