When traveling outside of your cellphone coverage area your phone jumps to other carriers networks to stay in service. Verizon made an attempt to shut out other carriers from being able to roam onto their network. Their claim was that it is mere business competition; you don’t have towers? Too bad! But a rule from 2011 that requires mobile data providers to offer roaming agreements to their competitors said No Way Jose! Roaming agreements are crucial for smaller carriers who risk losing customers if unable to provide service outside of their region. Basically on that 24 hr drive to Florida with the Fam next summer, You’ll be connected the whole way! Gotta thank the FCC for this one !!
