Editing Roaming (section)

== Technical definition ==
In more technical terms, roaming refers to ''the ability for a [[cellular network|cellular]] customer to automatically make and receive voice calls, send and receive data, or access other services, including home data services, when travelling outside the geographical coverage area of the home [[Telecommunications network|network]], by means of using a visited network''. For example: should a subscriber travel beyond their cell phone company's transmitter range, their cell phone would automatically utilize another phone company's service, if available.

The process is supported by the Telecommunication processes of mobility management, [[authentication]], [[authorization]] and [[accounting]] [[Bill (payment)|billing]] procedures (known as AAA or 'triple A').
