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.

TADIG Group Responsible for defining data interchange procedures. Main focus is billing including TAP, the Rejects & Returns Process, TAP Testing
TADIG Testing is a necessary step to: Check outbound roaming call detail records. Launch new roaming partners. Implement new roaming services with existing RPs:
GSM services GPRS roaming & MMS prepaid roaming 3G voice, 3G data, 3G prepaid roaming and 3G VT
TADIG Validation/Verification Type of Testing: TAP IN TAP OUT
