Improved Connections Across A Multitude Of Industries 

Companies are increasingly turning to SMS to communicate with their customers, it’s quick, cost effective, has an attractive open rate and is one of the most prominent forms of communication used today. Technology has made it easy to leverage SMS to ‘speak’ to customers, but maintaining delivery quality and honest support is a more difficult task to master.

Confronted with the age-old problem of being stuck in a chain of resellers, SMS77 found themselves in a perpetual loop of people who didn’t really know what they were doing when it came to sending SMS. To make matters worse, those they were dealing with had no direct network connections to make the job any easier. For a growing business like SMS77, getting direct connections is not an easy task – it’s neither readily accessible or affordable, so it was time for them to find a more cost effective and efficient solution.

SMS77 were looking for a few key things to help them make a decision on who to work with. First and foremost for them was quality of delivery, closely followed by the availability of transparent information, a comprehensive website that explained the possibilities of SMS well, and then good old fashioned honest support to back it all up.

With a need for quick and simple integration to enable reselling of SMS to smaller companies like fire departments, opticians, car service stations, or even owners of ‘smart homes’, SMS77’s goal was to build services around SMS, like automated daily messages or contact management.
