My father has an iphone 5 with PagePlus service. (verizon)
He lives in an old apartment building.
He has a signal near the windows, but really bad service everywhere else.
I want to get a cell phone signal booster.
I can't put an antenna on the roof and string down a cable to his apartment.
He doesn't have an internet box - he uses Optimum wifi. (He has a booster by his window to catch the signal and strengthen it to reach his laptop. )
I need something that goes by the window, but doesn't need to be plugged into a cable box.
Is there such a thing?
