An always-on packet switching service, mobile Internet providers have offered GPRS together with voice subscription packages for several years. Customers originally paid for GPRS service according to how much network bandwidth they used in sending and receiving data, but an increasing number of providers now offer flat-rate unlimited use packages.
GPRS is a slower alternative to EDGE 2.5G cellular networking. GPRS supports theoretical data rates up to 171 Kbps compared to the 473 Kbps speed of EDGE.
