I have been using the Kyocera DuraXT in the New York City area,since the Nextel shutdown back in June.People have been telling me that they have not been able to reach me,although they hear the dial tone ringing, not going straight to voicemail.The only way I know they called is if they leave me a voicemail, which sometimes I dont get until much later.I have called CS,and they say that there are not trouble tickets in my area.Anyone having the same issues?
