It has since become the largest communications operator in Qatar offering new technologies to the country including mobile, broadband, digital, and fiber internet services.

According to Ooredoo's 2016 disclosures, 68% of the company is owned by Qatar government-related entities, 10% by ADIA (UAE), and the remaining 22% is on the public market.

Its TV content providers include (but not limited to) StarzPlay, YuppTV, Alt Balaji, BluTV, Al Jazeera, EuroNews, FranceTV, ErosNow, FilmBox, Hopster, Spuul - and more are being added regularly.

[23] The home broadband and voice service is powered by WiMAX (Worldwide Interoperability for Microwave Access) technology.

In August 2007, Asiacell bid and won a 15-year national license, becoming the GSM telecom operator with the largest long-term network coverage in Iraq.

To handle new business operations, Asiacell also simultaneously established new executive offices in Baghdad, Basra, and other major cities in Iraq.

In June 2013, Ooredoo was chosen as one of the two successful applicants among 90 bidders to be awarded a license to operate in Myanmar, considered one of Asia's last remaining greenfield telecom markets.

Formal licenses were granted in January 2014, and Ooredoo pledged an investment of $15 billion to develop Myanmar's telecoms sector, with plans to cover 75 per cent of the population in five years.
