W G Pye and Company Limited was founded in Cambridge, England by William George Pye (1869-1949) in 1896. William George Pye was a scientific instrument maker previously employed at Cavendish Laboratories. In 1922, the company began a subsiduary producing radios which was sold in 1929 to George Orr Stanley, becoming Pye Radio Ltd (later Pye Ltd). Between 1936 and 1947, the company successfully concentrated on design and manufacture of military equipment. But in 1947, W G Pye & Co was sold to Pye Ltd, and in 1976, the Pye group of companies was bought by Philips.

In 1996, Philips telecom was sold to Cineven and its name changed to Simoco International. In 2002, various sell-offs meant that Simoco was placed into administration. In late 2002, the radio communications business was purchased by Team Telecom and became known as Team Simoco. In 2010, Team Telecom Group was formed and is now made up of 3 companies, including Simoco Group.
