How a 20-year Old Mobile Technology Protocol Is Revolutionising Africa
- joenot443 8y agoA fact not noted by the article "USSD messages are up to 182 alphanumeric characters long. Unlike Short Message Service (SMS) messages, USSD messages create a real-time connection during a USSD session. The connection remains open, allowing a two-way exchange of a sequence of data. This makes USSD more responsive than services that use SMS.[1]" Sounds like there are many great use-cases for this.
