Years ago we used a desktop application supplied by our telecommunications provided but found it to be very unreliable. So it was necessary to cease using the service and we opted to use our mobile phones for sending SMS text messages. Recently, we evaulated the time being spent and relooked at the desktop application to find there was no improvement So we tried SMS Broadcast and were amazed at it's features and reliability resulting in our purchasing bulk messages for our future use. In summary we are very pleased with SMS Broadcast and have no hesitation in recommending the service
