Connectivity
As a 2G phone supporting GSM bands 900/1800/1900, the A810 provided connectivity essentials of the time, including GPRS and EDGE for data services. Bluetooth 1.2 with A2DP allowed wireless audio streaming, while the USB 2.0 port enabled direct file transfers to a PC. However, the absence of WLAN and GPS meant internet browsing and location-based services were limited.
