Global Telecom Testing

Global Telecom Testing Mobile app testing service & phone number testing service, global roaming and IVR platform testing in 200 countries with more than 800 local testers.

Global Telecom Testing (GTT) was founded in 2007 specifically to address the lack of worldwide, in-country, live telephone number testing and IVR platform quality assurance testing for global companies. GTT is the only company in the world that in-country tests in 200 countries simulating the user experience with over 800 local testers. GTT enables its clients to establish a local presence and a highly reliable testing environment by leveraging the world's largest privately owned global footprint. Customers gain a universal understanding of their in-country user experience, so they can make actionable corrective decisions with measurable ROI and collaborate on those decisions both internally and with telecom carriers. Each year GTT's phone number testing services and toll free number testing service tests over 50,000 numbers performing 100,000+ test calls. GTT's User Acceptability Testing (UAT) tests over 600 worldwide IVR platforms and tests 400+ mobile apps & games annually. Our real world live mobile app testing services are the most reliable in the world. It all began with a handful of countries…
