You need to make that method static and public inside your activity.You can call that method like this:

ActivityName.mehtodName();

It will be much better if you put that method in your util class and call it from there.

You can create a Callback using an interface for calling that the activity method from BroadcastReceiver

interface MyCallback{

      public void doStuff();

}

Provide the CallBack in the BroadcastReceiver

public class MyBroadcastReceiver extends BroadcastReceiver{

   private MyCallback callback;

   public MyBroadcastReceiver(MyCallback callback){

       this.callback = callback;          //<-- Initialse it

   } 

   @Override
   public void onReceive(Context context, Intent intent) {

       callback.doStuff();                //<--- Invoke callback method
   }

}

Now implement the Callback in your Activity and override the method

MyActvity extends AppcompatActivity implements MyCallback {

   // Your Activity related code //
   // new MyBroadcastReceiver(this);    <-- this is how you create instance

   private void sendSMS(){
     // your logic to send SMS
   } 


   @Override 
   public void doStuff(){
     sendSMS();          //<--- Call the method to show alert dialog
   }

}
