ETSI and 3rd Generation Partnership Project (3GPP) standards, such as GSM and LTE, define supplementary service codes that make it possible to query and set certain service parameters (e.g., call forwarding) directly from mobile devices.
The services include voice (full and half-rate), supplementary services (call waiting, voice mail, three-way calling, call forwarding, and so on), data service (up to 9.6 kbit/s CSD), and packet-switched wireless data (up to 28.8 kbit/s PDC-P).
