Switzerland Phone Number Testing Services

We had been given incorrect information from our provider as to the in-country dialing patterns for each country. I appreciate the diligence and catching the errors and executing the correct dialing patterns.

Our customer came to us with an emergency they were having with their lines. GTT was able to get them tested so fast and we were able to troubleshoot and correct the issue with our customer so fast, that the customer barely had any down time on their lines

We started using the automated platform for our scheduled testing and newly rpvisioned numbers. It has been a life saver to run the tests off hours and have the results ready when I start the next morning. Gets a jump on my day and doesn’t tie up lines during normal business hours.

Highly recommended either for clients or remote testers!

The comprehensive testing data provided by GTT serves as a valuable resource, empowering us to analyze connectivity trends and proactively address potential roadblocks. Their team consistently exhibits a friendly and helpful demeanor in their correspondence, enhancing our partnership. The value that GTT’s testing services bring to our operations instills us with the confidence to deliver viable and dependable international telephony solutions to our customers. Together with GTT, we are committed to maintaining the highest levels of connectivity and reliability for our clientele.

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.
