About Us

When Sigma was first formed in 2003 we were a small firm dealing in telecommunication infrastructure services, our main focuses were network optimisation, planning and drive testing. Sigma enjoyed modest success in this field for over 10 years but then, in 2013 I remembered that for any business to truly thrive, grow and more importantly to succeed it needs to diversify and innovate in a way its competition and the rest of the industry does not.

It was at this point we decided to take SigmaTelecom across new horizons and we built up our infrastructure, made our investments, took risks and entered the VoIP market in 2014. Over the last couple of years Sigma has enjoyed unprecedented success in this industry we currently carry traffic worldwide and are connected with over 500 companies globally.

Of course ongoing success can never be guaranteed and we believe that for a company to truly maintain growth and diversity, it must strive to innovate not just internally but also externally in order to have a positive impact on its clients, customers, partners and the industry as a whole.

For this reason Sigma Telecom puts innovation and new ideas first, in the past year we have begun the process of taking the company into uncharted territory. We have begun development of multiple mobile applications for both Android and iOS devices, started building up infrastructure for our inception into both the data and SMS markets, we have also completed and launched a successful USSD program “ *400# ” in Turkey that allows customers to Top up their mobiles, pay their bills and purchase internet packages for their mobile devices.

I would be remiss if I did not attribute our accomplishments partly to our excellent and diverse work force, employees who are truly motivated, incentivised and satisfied with their position is part of what has led to Sigma Telecom’s unparalleled success and this will continue to be a contributing factor to our company’s advancement.

Additionally I would like to add that Sigma takes significant pride in its efforts to give back to the community with its numerous charitable actions including donations, projects, consultancy and any other service we may be able to offer the less fortunate.

To sum up Sigma Telecom has come a long way in the Telecommunications industry and I sincerely hope and believe we will go even further in the coming years. Just as Sigma Telecom 10 years ago and now seems incomparable we want this to be the case in the next 10 years as well.
