About O2 UK

O2 UK was called Cellnet back in 1985. Throughout 1985 and beyond, Cellnet was one of the lending mobile companies in the United Kingdom. Over a decade later, a company called BT acquired a portion of Cellnet, and this changed the landscape. Now, Cellnet was known as BT Cellnet. The new company now had a wireless division, but more changes were on the way. In 2002, the wireless division became a holding company, and this business introduced the O2 brand.
