what is t mobile edge

I can give you a brief explanation of what T-Mobile's EDGE network is.  EDGE, which stands for Enhanced Data Rate for GSM Evolution, was a 2G mobile communications technology used by T-Mobile and other carriers before moving to faster 3G and 4G networks.  It provided basic data connectivity and was a precursor to more advanced mobile data networks.  If you have specific questions or need more details, feel free to ask.
