一、鎖卡背景介紹
鎖卡即SIMLock,當手機開機啟動或者插入SIM卡時，手機modem側預置在NV項中的配置信息會與SIM卡中的信息做比對，檢測是否匹配。若匹配，則SIM卡可以正常使用。若不匹配，則SIM卡相關功能均無法正常使用，例如撥打電話、發送短信及上網等；或者是只能注冊2G網，不能注冊4G。
鎖卡的目的：一些運營商會要求控制某一類卡的使用，從而保護自己的利益（運營商定制機）
SIMLock鎖和圖案鎖，數字密碼鎖，PIN碼鎖，PUK鎖一樣，是Keyguard模塊中的一種鎖。
二、鎖卡的需求
鎖卡的需求方式有7種之多，常見的有NP鎖，NS鎖，CP鎖，SP鎖等
從安卓機器來看，目前最常用的是SP鎖（MCC/MNC），本文將解析SP鎖的加鎖流程
三、鎖卡流程解析
1.首先modem側檢測SIM卡的配置信息並與之作比對，若匹配則繼續加載SIM卡，若不匹配，則上報加鎖信息
2.RIL層檢測到modem上報的加鎖信息，然后發送給framework層，最終在AP層監測到事件：
3.AP層顯示出鎖卡界面，要求用戶輸入解鎖碼進行解鎖
四、相關流程圖

五、代碼解析
MTK平台已經支持SIMLock功能，但只能在代碼中寫固定的MCC/MNC，不能靈活配置。即一套代碼只能對應一套對應的鎖卡配置信息，對於手機廠商來說，顯然不滿足需求，發貨國家遍布全球，鎖卡配置信息均不同，代碼版本太多無法管理，故肯定要廢棄MTK的這套SIMLock功能。
（1）modem側客制化
涉及的代碼文件：
custom/modem/common/ps/custom_nvram_extra.c custom/modem/common/ps/customer_at_command.c custom/service/nvram/custom_nvram_sec.c custom/service/nvram/custom_nvram_sec.h interface/service/nvram/nvram_data_items.h service/nvram/src/nvram_factory_config.c service/nvram/src/nvram_main.c
a.擴展鎖卡配置信息的組數
custom_nvram_sec.h
#define SML_MAX_SUPPORT_CAT_N 50
初始化數組的時候，需要添加對應的默認配置信息

b.修改剩余解鎖次數
custom_nvram_sec.h
#define SML_MAX_RETRY_COUNT 10
c.擴展客制化的鎖卡NV項
例如MTK源生的鎖卡NV項已經可以通過工具查看及修改，這樣鎖卡就容易被破解。客制化自己的鎖卡NV項，即使MTK源生的被破解了，SIMLock功能依舊正常工作。
不過從Android 6.0來看，MTK已經在modem側做了處理，使用工具無法查看及修改該NV項了。
（1）先定義NV項
（2）對該NV項進行對應的初始化，參考源生的即可
d.擴展鎖卡的特殊需求（關聯鎖卡等）
由於源生的AT指令不能查詢鎖卡狀態信息，可以通過擴展AT指令來實現
如下代碼為擴展的AT+QSIM1的指令，查詢的信息包括鎖卡狀態，鎖卡配置信息，剩余次數等

（2）AP側客制化
SIMLock客制化工作量主要集中在modem側，AP側主要為界面顯示及AT指令的交互
a.AT指令的交互
查詢SIM卡狀態
查詢鎖卡狀態信息：是否鎖卡，鎖卡的配置信息（MCC/MNC），解鎖剩余次數等
發送PASSWORD到RIL側，解析解鎖是否成功的返回信息
b.用戶界面的顯示
提示用戶輸入解鎖碼
提示剩余解鎖次數
提示剩余時間可以繼續輸入解鎖碼
提示SIM卡永久被鎖
