| AT&T | 21800 Towncenter Plaza #266A | Signal starts out good, then consistently drops to zero bars.  Can't call or send text - no network connection.  Sometimes powering phone down and up will restore signal for a time, but not always.  Only part of Sterling, VA that seems to have this problem. | 2016 |
