SubscriptionInfo.java
SIM卡的信息就是SubscriptionInfo(Subscription Information)，比如iccid、MNC、MCC等，多张SIM卡就有多个SubscriptionInfo
//frameworks/base/telephony/java/android/telephony/SubscriptionInfo.java
public class SubscriptionInfo implements Parcelable {
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(mId); //数据库id，递增主键，每一个iccid的卡会占用1个id
dest.writeString(mIccId); //sim卡的iccid，每张sim卡是唯一的
dest.writeInt(mSimSlotIndex); //sim卡插入卡槽值，0是卡1，1是卡2，没有插入则是-1
dest.writeCharSequence(mDisplayName); //sim卡名称，用户可以自定义
dest.writeCharSequence(mCarrierName); //运营商名称
dest.writeInt(mNameSource); //名称来源，是用户设置或者是从sim卡读取（一般就是运营商名称）等
dest.writeInt(mIconTint); //sim卡图标染色值，tint的概念可以百度google
dest.writeString(mNumber); //sim卡关联号码
dest.writeInt(mDataRoaming); //sim卡是否启用数据漫游
dest.writeInt(mMcc); //mcc,移动国家码，3位数字，中国是460
dest.writeInt(mMnc); //mnc，移动网络码，2位数字，如00,01等，表示运营商
dest.writeString(mCountryIso); //国家iso代码
mIconBitmap.writeToParcel(dest, flags); //sim卡图标
}

subid
slotid或者phoneid是指卡槽，双卡机器的卡槽1值为0，卡槽2值为1，依次类推
subid：SubscriptionId(Subscription Identifier)。subid是数据库telephony.db的表siminfo的主键递增项，其中telephony.db在”/data/user_de/0/com.android.providers.telephony/databases”下

SubscriptionController—dumpsys isub
SubscriptionController 即SIM卡信息控制器，用Subscription的描述方式来自3GPP协议，SIM卡可被描述为Subscriber SubscriptionController 作为控制器，所以它所担负的责任是 SIM 卡信息的中转和管理工作
// frameworks/opt/telephony/src/java/com/android/internal/telephony/SubscriptionController.java
/**
*
* SubscriptionController to provide an inter-process communication to
* access Sms in Icc.

新SIM卡插入
当有一张新的SIM卡插入到手机，手机检测到有SIM卡插入，就会发起SIM卡数据的查询，UiccController将查询得到的数据，传递到SubscriptionController
ICCID IMSI
IMSI：国际移动用户识别码，是区别移动用户的标识，储存在SIM卡中，可用于区别移动用户的有效信息，通过IMSI可反查运营商、归属地、手机号码等信息，在接入网络时会到运营商服务器中进行验证。 格式：15位0-9的数字 ICCID：SIM卡卡号，是卡的标识，不作接入网络的鉴权认证，可在SIM卡卡后查询到。 格式：大多为19或20位0-9的数字，亦存在6位/12位的情况

UICC
UICC，全称 Universal Integrated Circuit Card，译作通用集成电路卡，主要用于
- 存储用户信息
- 鉴权密钥
- 短消
- 付费方式
- 联系人等信息
在UICC中可以包括多种逻辑模块，如：
- 用户标识模块（Subscriber Identity Module，SIM）
- 通用用户标识模块（Universal Subscriber Identity Module，USIM）
- IP多媒体业务标识模块（IP Multi Media Service Identity Module，ISIM）
- 智能IC卡模块（Removable User Identity Module，RUIM（UIM））
- 特殊RUIM（CSIM）
以上模块，实际上是网络升级换代所对应的产物。SIM用于GSM网络系统中，俗称2G网络。USIM也叫升级版SIM，多用于3G网络系统中。ISIM则是4G时代的产物。RUIM、CSIM是CDMA网络系统中的技术。
