I need a SMS platform that can be designed from open source that exits today. I need the SMS platform to be customized and it needs to work with all Major US Wireless Carriers. If you know how to do this please place a bid. The platform needs to be able to work with PSMS (premium SMS) and short codes, it also needs to be able to send and receive messages and connect to the sms aggregator. It must work with the wireless carriers billing systems. Looking to spend 300.
