Vodafone Portugal – Comunicações Pessoais, S.A., a full subsidiary of the Vodafone Group, is the second mobile operator in Portugal, both chronologically and in market share (34% in 2006). Its competitors are Optimus and TMN.

Vodafone Portugal was founded in 1991 as Telecel, Comunicações Pessoais, S.A. (Telecel) as it won the bid for Portugal's second GSM operator (after TMN).

The network went live in October 1992.

In 1996, the "pre-paid" concept was introduced with the launch of tariff plan Vitamina. Telecel also held a paging license and was leader in the 4-player paging business, using the brand Telechamada.

In January 2000, the indirect access fixed-line telephone service was launched, using Portugal Telecom's infrastrutctures and the 1091 prefix. It used the brands toq 1091 (for the home costumers; now discontinued in favour of Vodafone at Home/Vodafone Casa) and Voz Pri (for the business costumers; still used as part of the business solutions).

In May of the same year, Telecel entered the Internet Service Provider and web portal businesses under the brand Netc (pronounced "netcetera"). The business model was lifted from successful Freeserve, a British non-subscription ISP.

An automobile, autocar, motor car or car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods.

The term motorcar has also been used in the context of electrified rail systems to denote a car which functions as a small locomotive but also provides space for passengers and baggage. These locomotive cars were often used on suburban routes by both interurban and intercity railroad systems.

There are approximately 600 million passenger cars worldwide (roughly one car per eleven people). Around the world, there were about 806 million cars and light trucks on the road in 2007; the engines of these burn over a billion cubic meters (260 billion US gallons) of petrol/gasoline and diesel fuel yearly. The numbers are increasing rapidly, especially in China and India.
