Vodafone Limited, trading as Vodafone UK, is a British telecommunications services provider, and a part of Vodafone Group Plc, the world's second-largest mobile phone company. Vodafone is the third-largest mobile network operator in the United Kingdom, with 18.0 million subscribers as of July 2023, after O2 and EE, followed by Three. The country's first cellular phone call was made on the Vodafone network in 1985.

In 1981, Racal Electronics Group won its bid for the private sector UK Cellular licence, and created Racal Telecomms Division. The same year, Racal formed a joint venture with Millicom named 'Racal Vodafone'. The Vodafone name was first unveiled on 22 March 1984. Vodafone made the first cellular telephone call in the United Kingdom on 1 January 1985, from St Katharine Docks to Newbury, and launched the UK's first cellular network later that year. 'Vodapage' was launched two years later, providing 80% of the United Kingdom's population with a paging service, and a service called 'Vodata' was also launched for voice and data.
Racal Telecom was demerged from Racal Electronics in 1991, becoming Vodafone Group, and introduced the country's first GSM mobile phone network the same year. The company launched digital data, fax and a text messaging service with Vodata in 1994. Vodafone also began working with Globalstar to develop and launch a satellite to provide a Satellite phone service.
On 5 January 1999, Vodafone UK connected its 5 millionth customer. By the end of 1999 it had 8 million customers, rising to 12 million in 2001,
The first 3G voice call in the UK was made in April 2001 on the Vodafone UK network, with an initial network of 30 base stations in the Thames Valley set for the commercial launch in 2002. That same month Vodafone launched GPRS services.
