Why is there no cell phone signal in the restaurant

  • UptonBeck
    This happens all the time, every time when I go to a restaurant for dinner, I will find my cell phone signal is lost.But as soon as I get out of the hotel, the signal comes back on.What exactly is going on here?

    It's possible that the owner of the store used a cell phone jammer.What you're saying is very consistent with what happens when the jamming device is turned on.Mobile phone signals cannot be picked up in fixed areas
