Hi, I need your help with some information: Is true that the internet signal in Louisville KY is very bad for Cellular and smartphones? even if you send a message via facebook chat, this can arrive to the other person with 15 minutes delay? .. my girlfriend told me that, so is that true? is she deceiving me or cheating on me?

She told me that she was with her friends, even she invited me to chat with them via skype, and then “oh! Signal is bad”..I called her via Skype like 5 times and in the sixth she answered the call, but suddendly she appeared driving home.

She didn't answer my skype calls until she did from her car. Suddendly she appeared driving home telling me "I'm driving, I can't talk" but it supposed she was with her friend 4 minutes ago.

She told me that she sent that message 15 minutes before. Should I believe my girfriend?.
Give me your opinions please,

Really thankful you for your answers.
