使用TelephonyManager。

Use TelephonyManager.

由于Falmarri音符，你的将会的要使用的 getPhoneType 的首先，来看看你甚至处理一个GSM电话。如果你是，那么你也可以拿到SIM卡状态。

As Falmarri notes, you will want to use getPhoneType FIRST of all, to see if you are even dealing with a GSM phone. If you are, then you can also get the SIM state.

TelephonyManager telMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    int simState = telMgr.getSimState();
            switch (simState) {
                case TelephonyManager.SIM_STATE_ABSENT:
                    // do something
                    break;
                case TelephonyManager.SIM_STATE_NETWORK_LOCKED:
                    // do something
                    break;
                case TelephonyManager.SIM_STATE_PIN_REQUIRED:
                    // do something
                    break;
                case TelephonyManager.SIM_STATE_PUK_REQUIRED:
                    // do something
                    break;
                case TelephonyManager.SIM_STATE_READY:
                    // do something
                    break;
                case TelephonyManager.SIM_STATE_UNKNOWN:
                    // do something
                    break;
            }
