query match== SMS_ICC+MAX_MATCH_TYPE -> getSingleMessageFromIcc

getSingleMessageFromIcc -> smsManager.getAllMessagesFromIcc

getAllMessagesFromIcc -> iccISms.getAllMessagesFromIccEf

frameworks/base/telephony/java/com/android/internal/telephony/cdma/RuimSmsInterfaceManager.java

getAllMessagesFromIccEf -> mPhone.getIccFileHandler().loadEFLinearFixedAll(IccConstant.EF_SMS, response);

注：buildValidRawData ArrayList<SmsRawData> ret if(STATUS_ON_ICC_FREE) ret.add(null) else ret.add(new SmsRawData(...));

frameworks/base/telephony/java/com/android/internal/telephony/IccFileHandler.java

loadEFLinearFixedAll -> obtainMessage(EVENT_GET_RECORD_SIZE_DONE)

loadEFLinearFixedAll -> phone.mCM.iccIO(COMMAND_GET_RESPONSE, ...);

根据下面LOG中红色部分，就可以确定代码流程。

等到COMMAND_GET_RESPONSE返回，就要响应消息EVENT_GET_RECORD_SIZE_DONE了，

然后就调phone.mCM.iccIO(COMMAND_READ_RECORD,....); 然后在EVENT_READ_RECORD_DOWN消息中循环。
