Telefónica, empresa multinacional de telecomunicaciones, con sede central en la ciudad de Madrid.

Telus is one of the Big Three wireless service providers in Canada, with over 10 million mobile phone subscribers nationwide constituting about 30% of the total market. It is the incumbent local exchange carrier in the western Canadian provinces of British Columbia and Alberta, where it provides internet, television, and landline phone services. It also has a small wireline presence in eastern Quebec. Mostly because of recent acquisitions, more than 20% of Telus' sales now come from nontelecom businesses, most notably in the international business services, health, security, and agriculture industries. The firm has a 55% economic stake in Telus International.
