开启手机的SIM卡PIN码

我们都知道手机有锁屏密码，SIM也有自己的锁定密码，只是默认我们都很少去打开。

如今手机丢了或者偷了，跟一台硬件手机相比，我们更在乎手机里面的内容，有谁在乎过SIM卡的安全。按照现在的技术，连FBI都很难破解你iphone的锁屏密码了。

但是别人可以轻而易举取出你的SIM卡，然后装在自己的手机里，在你挂失SIM之前就登陆你的支付宝，你的微信，选择忘记密码，重置密码。接下来发生的事情，我想大家可想而知了。

iphone用户打开设置-电话-SIM卡PIN码，默认的PIN码为1234，你可以修改你的4位PIN码，这样你每次开关机，或者关闭开启飞行模式，你需要输入PIN码才能使用你的SIM卡。

需要注意的是输错3次PIN码，SIM会被锁，需要输入PUK码，PUK码就相当于SIM的身份证号，需要向运营商索取，运营商会核实你的资料，PUK码输错10次，这个SIM卡就报废了。

所以开启你的PIN码，并且像记女朋友男朋友生日一样牢记你的PIN码。
