What our customers are saying?

In roaming, the difficulty is to coordinate tests with roaming partners across the globe. With the GlobalRoamer solution we are able to connect faster, get problems solved faster and are able to give our subscribers the quality they deserve.[…] SIGOS is our partner right now and we will still be with SIGOS for a long time to come. We see so many benefits from the service and our subscribers are enjoying the service that we provide them as a result of this partnership.
Mohammed Buari, Senior Manager Interconnect & Carrier Relations, MTN, Nigeria
Keynote SIGOS with its global expertise and capabilities in end-to-end telecommunication testing is a prolific partner of choice.
Using their solutions provide us with an even more efficient and integrated management of our network and service delivery and strengthens the market competitiveness of individual operators and our entire Business Area.
Öykü Mengenli, Roaming Manager, TeliaSonera Eurasia
SITE and GlobalRoamer make us aware of which problems we might have with other networks BEFORE our customers are experiencing it.
Mluleki Ngcobo, Technical Support Manager Roaming, Cell C, South Africa

 

KPIS and Customer Experience (KQI) is extremly important- every day we look for that extra Kb or millisecond to make our services superior to any other network.
At Vodafone Spain, the Keynote SIGOS SITE system is connected to our network infrastructure e.g. directly to the core via IP, Iu and SS1, over the air via stationary and wireless probes and internationally, to well over 150 countries.
Salvador Pérez Martínez, Network & Services Management Manager, N&S Monitoring System, O&M Core, Vodafone, Spain
Only with GR we can test the throughout measurements that we couldn’t measure with any other system that we have. We are also very happy with the support and commercial team of Keynote SIGOS. It’s one of the best compared to other suppliers we have worked with.
Clara Casas Caballero, Network Quality Manager, Telefónica Spain
When we used SITE for the first time for active testing compliance, our quality was slightly below the industry measurement. After repeating three times the testing exercise, we saw a firm, positive and stable trend in improving the quality, and the last compliance showed us that we are above the industry standard. […] We are still focused in roaming on improving as much as possible to sustain the trend of growing and enlarging the KPIs, but our focus will most probably move more onto data. We have a global contract and very good relationships with SIGOS and we trust on SIGOS expertise in our exercise of tackling the roaming quality.
Emilia Nikolova, Manager Business Operations and Services, VimpelCom, Netherlands

 

When testing our LTE network using the SITE solution, we have managed to get some really good speed and set up some really good base lines for customer experience for our newly launched LTE network.
Jowed Khatiz, Network Performance Manager, VHA, Australia
We are using all of Keynote SIGOS solutions: GlobalRoamer, SITE and Professional Services Telecommunications and have gained major achievements. For example, the SIM Box detection service has helped us to detect off-net SIM boxes which are used by most illegal carriers and cannot be detected by other fraud management systems. Now also our Turkcell subsidiaries want to use Keynote SIGOS SIM Box Detection services.
Ömer Altinok, Group Revenue Assurance Manager, Turkcell, Turkey
We have SITE tools, we have GlobalRoamer tools, we have great power in our hands that can help us.
Alexander Tsivlin, Project Coordinator, MTS, Russia

 

With GlobalRoamer we’ve found several issues based on malfunctions on suppressed SMS services. With SITE we’ve located several internal topics in the network that had service impacts and we have been able to resolve these by doing deeper analysis with SITE. 7 years ago we chose the ideal partner in Keynote SIGOS. Keep on going like this! It’s really a pleasure to see how you develop and how our needs are covered, before we are even aware that we have them.
Michael Thaler, Technical Product Manager Mobile Proxy, Swisscom, Switzerland
We used to have very extensive quality measurement and adding end-to-end testing in 2006 with GlobalRoamer has helped us enormously to find carriers that look good price-wise, traditional quality-wise, but fail on other parameters that we couldn’t measure before. So a major achievement is better supplier choice, but also that we are now able to mimic the quality for many of our key account mobile groups and be pro-active that way.
Jacky Droushoudt, AVP Quality of Service, PCCW Global – Gateway Communications, Belgium
SITE has been an integral part for Roaming and GRQ Global Roaming and we rely on Keynote SIGOS as a trusted business partner to accomplish our strategies for Quality of Service.
Takis Papadakis, Principal Quality Assurance Manager, Vodafone Roaming Services, Luxembourg

 

Every minute you need to monitor and check. For this purpose you have to perform periodic tests, on demand tests, network diagnosis tests, content tests. SITE is very crucial for service quality monitoring.
Selim Aslan, Test & Acceptance Project Manager, Vodafone, Turkey
…three different groups within Turkcell that are using SIGOS actively: the Service Network, the Core Network GPRS Operation Group and of course us as Roaming Group. Additional Investment is not necessary at all…..
Esin Say Polat, Roaming and Network Applications Manager, Turkcell, Turkey
… SIGOS solution will help us to attend this famous target, which is to give the best quality of service to our subscribers..
Abbes Mokeddem Bouziane, Manager, Wataniya Telecom, Algeria

 

Telefónica is enabling the first multi-operator LTE roaming experience together with operator partners from over 15 different countries. An experience which places Telefónica in a strong position to close the commercial agreements necessary in order to guarantee anywhere in the world the same LTE service quality as at home.
Enrique Blanco, Global CTO, Telefónica, Italy
The SIGOS system covers all our needs in different departments at MTS Ukraine, e.g. our Quality and Customer Experience Department uses the system to measure network quality and KPIs for quality of service testing. Interconnect & Carrier Relations Department and Anti-Fraud Department use SITE System for SIM Box and Fraud Detection, Roaming Department uses GlobalRoamer for roaming testing, while as the Testing Department uses the SITE System for test call generation, revenue assurance.
Ievgeniia Molchanova, Head of Testing Department, MTS, Ukraine
