The acronym GPRS stands for General Packet Radio Service in mobile communications. It is a packet-oriented mobile data standard that enables transmission of data over cellular networks, allowing mobile devices to access the internet and send/receive SMS messages. GPRS provides moderate speed data transfer and is considered a bridge between circuit-switched data services and more advanced technologies like 3G and 4G. By utilizing GPRS, mobile users can browse, email, and access multimedia content on their devices.
