O2 started in the home broadband market in 2007 and a year after; it introduced its mobile broadband service.

In 2006, O2, or Telefonica Europe was formed when the British company united with the Telefónica, a Spanish telecommunications giant. However, the mobile company history spans much further back than this. It was firstly recognized as BT Wireless and later on as BT Cellnet, as the BT’s first mobile network provision service.

However, in 2001 a de-merger happened, the company gotten freedom from BT and relabeled as O2. For 5 years, they kept this freedom status but the latest procurement by Telefónica has faked links between other European telecommunications companies, especially the Czech Republic and Germany.
