Worldwide Phone Number Testing

GTT’s local testers make live outbound originating test calls from worldwide cities using local landline and mobile networks in order to verify that the local numbers are operational, and to detect issues

Global Roaming Testing

When launching mobile services in new countries, it is imperative to in-country locally test to ensure all services are operational. Improper network provisioning, network inaccessibility, and carrier activation failures are common in-country roaming issues that are NOT detected by using automated testing.

IVR Platform Testing

In-Country IVR testing of newly installed and/or repaired worldwide IVR platforms confirms they are operational or not. GTT’s local testers make live quality assurance test calls to your IVR platforms after they have been installed and/or repaired. This verifies the user experience, menu flow, and full functionality, which ensures positive customer experience, customer retention, and protects revenue.

WiFi HotSpot Testing

GTT’s local staff in-country field tests your WIFI hotspots for signal strength, functionality, and connectivity. Customers coordinate detailed testing scenarios with GTT local staff.
