When they see SENDER ID in their message inbox list, the majority of users do not open the SMS and dismiss it. So we've created a SIM-based SMS solution that allows you to execute promotional marketing with a high view rate and no SENDER ID. We have a huge SIM-based SMS sending system where users receive SMS without a Sender ID and see a number. We discovered that the SMS view ratio is 99 percent by examining the data. SIM-based SMS are sent with standard priority, but they provide a 99 percent view result in front of clients, making them extremely trustworthy for promotional and advertising SMS.
