  • Hutchison 3UKStuart Waton, Revenue Assurance Team Lead

    Having used BluGem TCGs for several years to ensure completeness and accuracy for domestic Retail usage, we were confident that they would be the right choice for our rapidly growing Wholesale business. Thanks to BluGem’s experience and flexibility, process and leakage issues were identified and resolved quickly that have paid for the service several times over, and we had no hesitation in recently extending that contract to support our Wholesale business through continuing growth and transformation.

  • Sure (CIIM) Channel Islands & Isle of ManMarco Cassiano, Fraud and Revenue Assurance

    We selected BluGem to test our IMS platform based on the accuracy of their IMS/SIP test call solution and independent CDR usage and rating verification services. BluGem detected several issues from the testing, which were subsequently fixed by Sure and retested by BluGem. Our assessment of the resolved issues presented a positive ROI for the test service that was delivered on time and concluded with a comprehensive test analysis report. I would recommend BluGem for their dynamic approach to delivering solutions and results on time and for their innovative TCG services supporting IMS/SIP technologies.

  • Ultra MobileRizwan Kassim, Co-Founder and Chief Strategy Officer

    As America’s Fastest Growing Company in 2015, we often look outside our own team to solve complex problems in a hurry. BluGem was able to offer a complete and thoughtful assessment - generating test calls to ensure that our wholesale carrier, international carrier and local soft switch CDRs and billing were all compliant. I wouldn’t hesitate to use them again.

  • National Telecommunication CorporationHassan Mukhtar, Head Quality of Service Section

    The National Telecommunication Corporation haven been using the BluGem Test Call solution since 2012, which is a powerful system, easily to administrate in addition to its flexibility when it comes to tariff planning. As a Telecom Regulator this system has helped us to monitor and verify operators' charging systems. Moreover, the TCG solution has helped to discover and provide us with verification of the causes of the leakage in billing from one of the mobile operators. Additional to that, we have been totally satisfied with the quick support and response of the service.

  • Jersey TelecomAdrian Youd, Head of Fraud and Revenue Assurance

    Jersey Telecom have been delighted with the performance of BluGem's Test Call Generator. It was deployed and ready for use in three days, and its intuitive design made staff training easy. It has helped us become more efficient and effective - we now spend less time on housekeeping tasks and more on analysis. Overall, we are glad we made the move from our previous supplier.
