Cellular roaming has been transformed over recent years! It has shifted from a premium, high cost service that was targeted at business users, to an essential service used by consumers to keep in touch, keep entertained and update their social media profiles when they are travelling. However, at its foundation is the requirement that all participants broadly align in terms of delivering coverage and connectivity-centric value propositions. Moreover the roaming service provided by an access network is assumed to be monetized by usage fees.
