获取sim卡状态流程： 
getSIMStatus()
CommandsInterface.java (frameworks\base\telephony\java\com\android\internal\telephony\gsm)
接口 public interface CommandsInterface 中有
void getSimStatus(Message result);
RIL.java (frameworks\base\telephony\java\com\android\internal\telephony\gsm)
public final class RIL extends BaseCommands implements CommandsInterface
RIL 类实现了 CommandsInterface 接口
getSimStatus(Message result)
RILRequest rr = RILRequest.obtain(RIL_REQUEST_GET_SIM_STATUS, result);
send(rr);
rild 程序流程 
static void processCommandsCallback(int fd, short flags, void *param)
processCommandBuffer(p_record, recordlen);
status = p.readInt32(&request);
pRI->pCI = &(s_commands[request]); 
pRI->pCI->dispatchFunction(p, pRI);
因为有 {RIL_REQUEST_GET_SIM_STATUS,dispatchVoid, responseInts},
所以执行的是 Ril.cpp (hardware\ril\libril) 文件中的函数：
static void dispatchVoid (Parcel& p, RequestInfo *pRI)
s_callbacks.onRequest(pRI->pCI->requestNumber, NULL, 0, pRI);
//Reference-ril.c (hardware\ril\reference-ril):
case RIL_REQUEST_GET_SIM_STATUS：
getSIMStatus()
err = at_send_command_singleline("AT CPIN?", " CPIN:", &p_response);
return ret;
//Ril.cpp (hardware\ril\libril)
RIL_onRequestComplete(t, RIL_E_SUCCESS, &simStatus, sizeof(simStatus));
sendResponse(p);
sendResponseRaw(p.data(), p.dataSize());
blockingWrite(fd, data, dataSize);
==========================================================================================
pin码验证流程：
KeyguardViewManager.java (frameworks\policies\base\phone\com\android\internal\policy\impl
show()
mKeyguardView = mKeyguardViewProperties.createKeyguardView(mContext, mUpdateMonitor, this);
new LockPatternKeyguardView(context, updateMonitor,mLockPatternUtils, controller);
mUnlockScreen = createUnlockScreenFor(unlockMode);
createUnlockScreenFor(UnlockMode unlockMode)
如果 unlockMode == UnlockMode.SimPin
那么 new SimUnlockScreen(mContext,mUpdateMonitor,mKeyguardScreenCallback);
updateScreen(mMode);
由 SimUnlockScreen 类的
public void onClick(View v)
mOkButton 执行的是 checkPin()
new CheckSimPin(mPinText.getText().toString())
//PhoneInterfaceManager.java (packages\apps\phone\src\com\android\phone) 
supplyPin(String pin)
return checkSimPin.checkPin(pin);
mSimCard.supplyPin(pin, callback);
//private final SimCard mSimCard;
//因为类 GsmSimCard 实现了 SimCard 接口所以实际执行的是：
//GsmSimCard.java (frameworks\base\telephony\java\com\android\internal\telephony\gsm)文件中的
public void supplyPin (String pin, Message onComplete)
phone.mCM.supplySimPin(pin,obtainMessage(EVENT_PINPUK_DONE, onComplete));
//RIL.java (frameworks\base\telephony\java\com\android\internal\telephony\gsm)
public void supplySimPin(String pin, Message result)
RILRequest rr = RILRequest.obtain(RIL_REQUEST_ENTER_SIM_PIN, result);
send(rr); //通过socket 向 rild 发送 RIL_REQUEST_ENTER_SIM_PIN 请求
rild端处理流程： 
static void processCommandsCallback(int fd, short flags, void *param)
processCommandBuffer(p_record, recordlen);
status = p.readInt32(&request);
pRI->pCI = &(s_commands[request]); 
pRI->pCI->dispatchFunction(p, pRI);
因为有 {RIL_REQUEST_ENTER_SIM_PIN, dispatchStrings, responseVoid},
所以执行的是 Ril.cpp (hardware\ril\libril) 文件中的函数：
static void dispatchStrings (Parcel &p, RequestInfo *pRI)
s_callbacks.onRequest(pRI->pCI->requestNumber, pStrings, datalen, pRI);
此处的 pRI->pCI->requestNumber 为 RIL_REQUEST_ENTER_SIM_PIN
//Reference-ril.c (hardware\ril\reference-ril)
static void onRequest (int request, void *data, size_t datalen, RIL_Token t)
case RIL_REQUEST_ENTER_SIM_PIN:
requestEnterSimPin(data, datalen, t);
err = at_send_command_singleline(cmd, " CPIN:", &p_response);
err = at_send_command_full (command, SINGLELINE, responsePrefix,...);
err = at_send_command_full_nolock(command, type,responsePrefix,...);
err = writeline (command);
written = write (s_fd, s cur, len - cur);//往串口写数据
RIL_onRequestComplete(t, RIL_E_SUCCESS, NULL, 0);

开启sim卡的pin
EnableSimPinScreen.java
rild端处理流程： 
static void processCommandsCallback(int fd, short flags, void *param)
processCommandBuffer(p_record, recordlen);
status = p.readInt32(&request);
pRI->pCI = &(s_commands[request]); 
pRI->pCI->dispatchFunction(p, pRI);
因为有 {RIL_REQUEST_ENTER_SIM_PIN, dispatchStrings, responseVoid},
所以执行的是 Ril.cpp (hardware\ril\libril) 文件中的函数：
static void dispatchStrings (Parcel &p, RequestInfo *pRI)
s_callbacks.onRequest(pRI->pCI->requestNumber, pStrings, datalen, pRI);
此处的 pRI->pCI->requestNumber 为 RIL_REQUEST_ENTER_SIM_PIN
