you have to constantly advertise your location to get cell service (by design, didn't have to be so)

stores scan your phone radio and also aggregate this data to map your store visit.

this was all done with credit cards in the 50s and then outlawed, hence: reward programs.

so, can't wait for Verizon to offer a cell coverage reward program that is nothing but a waiver to your data, just like reward programs from credit cards of yore.
