Value Added Services such as SMS (Short Message Service) and USSD (Unstructured Supplementary Service Data) are also some of the services Pearl System offers to her customers. The Bulk SMS service enables business to use their SMS credit to send one or multiple messages to mobile subscribers at a small fee. It also supports a 2-way messages service for businesses that would like to receive messages from subscribes on a dedicated hotline number. The USSD service enabled businesses to create session-based menus so their customers can access services straight from their mobile phone. USSD has been one of the older technologies that has been around since the beginning of GSM networks and it’s still heavily supported today by any mobile carrier networks and almost any cell phone.
