Brenda housemaster

My colleague used Global Telecom Testing for his new mobile app in 89 countries. I used to rely automated testing but he told me about GTT and I was surprised to learn that GTT uses live testers. I had them test my toll free number list of 2,900 numbers and I got back a 100% accurate result, even in countries like Bangladesh, Latvia, the UK, Nicaragua, Ghana, Bahrain, Korea, and Croatia. Thank you Stephen Levenson for your terrific service.

Richard Artex

GTT has local testers in all the countries I wanted to test in and I was able to get accurate results for my mobile apps and toll free phone numbers. First I used their automated testing system to save some money. The gave me credits for failed calls and then I used their inn country international human testers for the rest of the numbers to get complete accurate results. Their mobile app testing service was great too as the actually had professional testers in each country I tested in.
