Answer 1

You'll need to do it in two steps. something like this:

A. Query SMS database by address to obtain your SMS's message id:

 String numberFilter = "address='"+ phoneNumber + "'";
 String messageid = null;
 Cursor cursor = mContext.getContentResolver().query(Uri.parse("content://sms/"), 
              null, numberFilter, null, null);

 if (cursor.moveToFirst()) {
      messageid = cursor.getString(0);
 }

B. Delete SMS using message id:

getContentResolver().delete(Uri.parse("content://sms/" + messageid), null, null);

Now, for multiple deletions. You reported multi-deletion failed when you use cursor iteration (while cursor.moveToFirst()). I never tried it but I assume

It has something to do with cursor invalidated after delete. Try instead to restart the cursor before each delete, something like this:

 for (;;) {
     // restart cursor before each delete
     String messageid = null;
     Cursor cursor = mContext.getContentResolver().query(Uri.parse("content://sms/"), 
                  null, numberFilter, null, null);

     if (!cursor.moveToFirst()) {
       break; // nothing more to delete
     }

     // delete single record
     messageid = cursor.getString(0);
     getContentResolver().delete(Uri.parse("content://sms/" + messageid), null, null);
 }

You will need write SMS permission:

<uses-permission android:name="android.permission.WRITE_SMS"/>
