在sim卡状态改变的广播接收着中：
String iccState = intent.getStringExtra(IccCard.INTENT_KEY_ICC_STATE);
iccState表示当前卡的状态，这些状态在IccCard中定义了常量，如下：
/* The extra data for broacasting intent INTENT_ICC_STATE_CHANGE */
static public final String INTENT_KEY_ICC_STATE = "ss";
/* NOT_READY means the ICC interface is not ready (eg, radio is off or powering on) */
static public final String INTENT_VALUE_ICC_NOT_READY = "NOT_READY";
/* ABSENT means ICC is missing */
static public final String INTENT_VALUE_ICC_ABSENT = "ABSENT";//没插卡的时候是这个状态
/* LOCKED means ICC is locked by pin or by network */
//被pin码锁住或被network锁住，pin码一般默认值为1234，如果pin码锁开启了，那么手机再开机的时候需要输入pin码后才能进入手机，否则无法进手机，当然拔了卡就没问题了，另外pin码尝试次数3次，如果3次失败，就要用puk码来解，puk码可以尝试10次，失败后sim卡报废。puk码在办卡的时候在卡上有。
static public final String INTENT_VALUE_ICC_LOCKED = "LOCKED";
/* READY means ICC is ready to access */
static public final String INTENT_VALUE_ICC_READY = "READY";
/* IMSI means ICC IMSI is ready in property */
static public final String INTENT_VALUE_ICC_IMSI = "IMSI";//此状态表示可以读取imsi号了
/* LOADED means all ICC records, including IMSI, are loaded */
static public final String INTENT_VALUE_ICC_LOADED = "LOADED";
/* The extra data for broacasting intent INTENT_ICC_STATE_CHANGE */
static public final String INTENT_KEY_LOCKED_REASON = "reason";
/* PIN means ICC is locked on PIN1 */
static public final String INTENT_VALUE_LOCKED_ON_PIN = "PIN";
/* PUK means ICC is locked on PUK1 */
static public final String INTENT_VALUE_LOCKED_ON_PUK = "PUK";
/* NETWORK means ICC is locked on NETWORK PERSONALIZATION */
static public final String INTENT_VALUE_LOCKED_NETWORK = "NETWORK";
/* PERM_DISABLED means ICC is permanently disabled due to puk fails */
static public final String INTENT_VALUE_ABSENT_ON_PERM_DISABLED = "PERM_DISABLED";
