Sometimes I'll get a missed call that doesn't show up as a missed call. The only reason I'll know about it is because my boyfriend will tell me he tried to call me and the phone rang then went to voicemail. Only I never heard my phone rang. Or call went straight to voicemail. This has happened so many times that I'm thinking of switching to metro PCs. But before i do I wanna know if its a carrier problem or my phone? I have an Alcatel one touch idol3 5.5.
