The company's O2 (UK) subsidiary is a leading mobile phone operator in the UK, with more than 14 million customers, and O2 also has customers in Germany (8.4 million) and Ireland (1.5 million). The company has introduced 3G service and its O2 Airwave offers services to rescue workers in the UK. The company shortened its name from mmO2 to O2 in 2005, but had already been using the O2 moniker (as in that oh-so-essential element, oxygen) for all holdings except its Manx Telecom unit. Spain's Telefónica acquired control of O2 in 2006. History O2 is a leading provider of mobile services to consumers and businesses in the UK.
