Japan Phone Number Testing
and Toll Free Number Testing
Global Telecom Testing’s (GTT) comprehensive live phone number testing and toll free number testing in Japan ensures that all phone numbers and toll free numbers are functioning properly. Real-time phone calls are the most important testing benchmarks when testing in Japan because only this testing accurately simulates the in-country user experience.
Live testing is performed by testers in Japan with all the variables and idiosyncrasies that customers encounter, such as, geographic restrictions, service limitations, incorrect dialing codes, etc. In-Country testing ensures that Japan phone numbers and toll free numbers are problem-free, the message is correct, language and dialect is correct, voice and DTMF prompts are working, and that IVR platforms are functioning properly.
