About
O2 has its origins back in the very earliest days of mobile telephony in the mid-1980’s under the stewardship of BT (then British Telecom) when the brand was known as Cellnet (later BT Cellnet when it became part of BT Wireless, a group of subsidiaries owned by BT).
In late 2001, BT Cellnet demerged from BT and was relaunched in May 2002 as O2. This brand name (the chemical symbol for unbound oxygen) was chosen since, like oxygen, what the company provides could be considered essential.
In 2005, Telefonica took O2 over although they stayed in the UK and retained their basic management structure and branding.
With over 23 million customers, O2 runs 2, 3 and 4G networks across the country and owns half of Tesco Mobile. There are some 450 O2 retail stores, and the company has a good satisfaction record according to the most recent statistics from Ofcom (see below).
