I concur with what AndroidxGuy has already said; however...
I have been having a lot of problems making / receiving phone calls lately as well. Mostly dropped calls though. I have been wondering if Metro is becoming a victim of their own success? Putting too many users on their network?
I have been using Metro for many years now, and I never really remember dropping any more phone calls than I ever did on any other carrier. Are we just having bad luck here, or is Metro overextending their network? I am in Tampa area (Pinellas County, actually), FL.
