O2 X1b Connectivity and Audio

Connectivity and Audio

The O2 X1b's connectivity features reflect its vintage, with support for GSM 900/1800/1900 2G bands and GPRS. However, it lacks EDGE capabilities, WLAN, and positioning, which further limits its functionality in terms of modern-day internet connectivity. It includes Bluetooth for basic wireless connections, but the absence of a 3.5mm audio jack means users cannot use standard headphones. Sound is delivered via a loudspeaker, with vibrational alerts and downloadable polyphonic ringtones available for customization.
