              int iRow;
              for (iRow = 0; iRow < dataGridView1.RowCount; iRow++)
              {
                  if (dataGridView1[0, iRow].Value != DBNull.Value && dataGridView1[0, iRow].Value != null && dataGridView1[0, iRow].Value != null && dataGridView1[0, iRow].Value.ToString() != "0")
                  {
                        template = SendSMS(dataGridView1[0, iRow].Value.ToString());

Presumably SendSMS() does not return a value, so you should be using it like this:

C#

if (dataGridView1[0, iRow].Value != DBNull.Value && dataGridView1[0, iRow].Value != null && dataGridView1[0, iRow].Value != null && dataGridView1[0, iRow].Value.ToString() != "0")
{
   SendSMS(dataGridView1[0, iRow].Value.ToString());
}
