change this line

String action = intent.getAction();
contact = intent.getExtras().getString("contact");

to 

Intent intent = getIntent();
contact = intent.getStringExtra("contact");

Make sure the phNo is of type String. If not, use getInt() in your BroadcastReciever.

You might want to add a String in extras, and retrieve back in String. If the type of phNo variable is int, then you should retrieve the extra value in the form of int only.

In main activity use this code to start broadcast receiver 

Intent intent = new Intent("package.action.string");
intent.putExtra("extra", phoneNo); \\ phoneNo is the sent Number
sendBroadcast(intent);

In the broadcast reciver use this code

public void onReceive(Context context, Intent intent) {
 String action = intent.getAction();

 Log.i("Receiver", "Broadcast received: " + action);

 if(action.equals("package.action.string")){
   String state = intent.getExtras().getString("extra");

  }
}

NOTE : Donot forget to declare your Broadcast receiver in manifest file 

<receiver android:name=".SmsReceiver" android:enabled="true">
<intent-filter>
    <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    <action android:name="package.action.string" />
    <!-- and some more actions if you want -->
</intent-filter>
</receiver>
