USSD operation mode documentation
Documentation has been updated with a new entry explaining usage of the library in Unstructured Supplementary Service Data (USSD) in SMPP protocol.
What is USSD?
USSD messaging (Unstructured Supplementary Service Data) is a protocol used by mobile networks to communicate with the service provider's computers. Unlike Short Message Service (SMS) messages, USSD messages create a real-time connection during a USSD session. The USSD session remains open during exchange of messages, allowing a two-way exchange of a sequence of data. This makes USSD more responsive than services that use SMS.
