Connectivity
The Sony Ericsson txt supports GSM 2G network technology and provides modest connectivity options like Wi-Fi 802.11 b/g, Bluetooth 2.1 with A2DP, and a microUSB 2.0 port. It lacks advanced positioning systems such as GPS, but it includes a stereo FM radio with RDS, catering to users who enjoy listening to live radio broadcasts. The inclusion of native Facebook and Twitter clients speaks to the device's emphasis on social connectivity, a feature that was increasingly important at the time of its release.
