For application builders and OEMs who need SS.7 access for their applications we provide an easy way to implement this. For querying the mobile network for specific subscriber data such as the position, presence, IMSI, MSRN of a specific MSISDN, you can enhance your application with the Network Access Function (NAF) product or with the External Access (XS) platform. The XS platform allows for personlized and sponsored SMS services.
