If you travel a lot, it is unlikely that you will only pass through 2G sites. As a result, there may be an issue with your device that has to be resolved. Your phone may be stuck on EDGE because your current house or location lacks adequate signal strength; but, if you relocate to a new area, it will operate correctly. When the signal quality improves, T-Mobile will switch you to the quickest available network. A software setting might possibly be at blame for the problem. Many mobile devices offer these features, which allow you to switch to a lower-bandwidth connection, such as EDGE or 2G, to save battery. Examine your phone's settings. It generally displays when your battery saver is on. Turn off your battery saver to guarantee that your gadget runs smoothly. If this does not happen automatically for you, there might be a problem with your mobile device or the connection. Some basic troubleshooting procedures may assist you in reconnecting to your network.
