Roaming General term in wireless telecommunications that refers to the extending of connectivity service in a location that is different from the home location where the service was registered. The ability for a 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 network, by means of using a visited network.

Roaming Broad roaming coverage is essential for every mobile operator. Each new roaming agreement, however, requires complex setups and

extensive testing. The tests are performed to check and confirm that all call event details are included in a syntactically correct TAP file.
