Check if Sim Card is installed

Question

Hello,

I wonder if it is possible to check if the sim card on the device is installed on Android.

Answer 1

A quick consultation in the documentation reveals the function TelephonyManager.getSimState(). Can be used like this:

final TelephonyManager telephony = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
if (telephony.getSimState() == TelephonyManager.SIM_STATE_READY) {
    // ...
}

The value returned is one of the following:

SIM_STATE_UNKNOWN // Em transição entre dois estados
SIM_STATE_ABSENT
SIM_STATE_PIN_REQUIRED
SIM_STATE_PUK_REQUIRED
SIM_STATE_NETWORK_LOCKED
SIM_STATE_READY

You can even set a callback to notify that the SIM situation changes:

telephony.listen(new PhoneStateListener() {
    @Override
    public void onServiceStateChanged(ServiceState serviceState) {
        // Verifique aqui a situação do SIM
    }
});
