Vodafone Group plc /ˈvoʊdəfoʊn/ is a British multinational telecommunications company, with headquarters in London. It predominantly operates services in the regions of Asia, Africa, Europe, and Oceania. Among mobile operator groups globally, Vodafone ranked fifth by revenue and second (behind China Mobile) in the number of connections (469.7 million) as of 2016.

Vodafone owns and operates networks in 26 countries and has partner networks in over 50 additional countries. Its Vodafone Global Enterprise division provides telecommunications and IT services to corporate clients in 150 countries.

Vodafone has a primary listing on the London Stock Exchange and is a constituent of the FTSE 100 Index. It had a market capitalisation of approximately £52.5 billion as of 10 February 2016, the eighth-largest of any company listed on the London Stock Exchange. It has a secondary listing on NASDAQ.

The name Vodafone comes from voice data fone (the latter a sensational spelling of "phone"), chosen by the company to "reflect the provision of voice and data services over mobile phones".

The evolution of Vodafone started in 1982 with the establishment of the Racal Strategic Radio Ltd subsidiary of Racal Electronics, the UK's largest maker of military radio technology, which formed a joint venture with Millicom called 'Racal', which evolved into the present day Vodafone.

In 1980, Sir Ernest Harrison OBE, the then chairman of Racal Electronics, agreed to a deal with Lord Weinstock of the General Electric Company to allow Racal to access some of GEC's tactical battle field radio technology. The head of Racal's military radio division, Gerry Whent, was briefed by Ernest Harrison to drive the company into commercial mobile radio. Whent visited a mobile radio factory run by General Electric (unrelated to GEC) in Virginia, USA the same year to understand the commercial use of military radio technology.

Jan Stenbeck, head of a growing Swedish conglomerate, set up an American company, Millicom, Inc. and approached Racal's Whent in July 1982 about bidding jointly for the UK's second cellular radio licence. The two struck a deal giving Racal 60% of the new company, Racal-Millicom, Ltd, and Millicom 40%. Due to UK concerns about foreign ownership, the terms were revised, and in December 1982, the Racal-Milicom partnership was awarded the second UK mobile phone network license. Final ownership of Racal-Millicom, Ltd was 80% Racal, with Millicom holding 15% plus royalties and venture firm Hambros Technology Trust holding 5%. According to the UK Secretary of State for Industry, "the bid submitted by Racal-Millicom Ltd… provided the best prospect for early national coverage by cellular radio."

Vodafone was launched on 1 January 1985 under the new name, Racal-Vodafone (Holdings) Ltd, with its first office based in the Courtyard in Newbury, Berkshire, and shortly thereafter Racal Strategic Radio was renamed Racal Telecommunications Group Limited. On 29 December 1986, Racal Electronics issued shares to the minority shareholders of Vodafone worth GB£110 million, and Vodafone became a fully owned brand of Racal.

On 26 October 1988, Racal Telecom, majority held by Racal Electronics, went public on the London Stock Exchange with 20% of its stock floated. The successful flotation led to a situation where Racal's stake in Racal Telecom was valued more than the whole of Racal Electronics. Under stock market pressure to realise full value for shareholders, Racal demerged Racal Telecom in 1991.

On 16 September 1991, Racal Telecom was demerged from Racal Electronics as Vodafone Group, with Gerry Whent as its CEO.

In July 1996, Vodafone acquired the two-thirds of Talkland it did not already own for £30.6 million. On 19 November 1996, in a defensive move, Vodafone purchased Peoples Phone for £77 million, a 181 store chain whose customers were overwhelmingly using Vodafone's network. In a similar move the company acquired the 80% of Astec Communications that it did not own, a service provider with 21 stores.

In January 1997, Gerald Whent retired and Christopher Gent took over as the CEO. The same year, Vodafone introduced its Speechmark logo, composed of a quotation mark in a circle, with the O's in the Vodafone logotype representing opening and closing quotation marks and suggesting conversation.

On 29 June 1999, Vodafone completed its purchase of AirTouch Communications, Inc. and changed its name to Vodafone Airtouch plc. The merged company commenced trading on 30 June 1999. To gain anti-trust approval for the merger, Vodafone sold its 17.2% stake in E-Plus Mobilfunk. The acquisition gave Vodafone a 35% share of Mannesmann, owner of the largest German mobile network.

On 21 September 1999, Vodafone agreed to merge its US wireless assets with those of Bell Atlantic Corp to form Verizon Wireless. The merger was completed on 4 April 2000, just a few months prior to Bell Atlantic's merger with GTE to form Verizon Communications, Inc.

In November 1999, Vodafone made an unsolicited bid for Mannesmann, which was rejected. Vodafone's interest in Mannesmann had been increased by the latter purchase of Orange, the UK mobile operator. Chris Gent would later say Mannesmann's move into the UK broke a "gentleman's agreement" not to compete in each other's home territory. The hostile takeover provoked strong protest in Germany, and a "titanic struggle" which saw Mannesmann resist Vodafone's efforts. However, on 3 February 2000, the Mannesmann board agreed to an increased offer of £112 billion, then the largest corporate merger ever. The EU approved the merger in April 2000 when Vodafone agreed to divest the 'Orange' brand, which was acquired in May 2000 by France Télécom.

On 28 July 2000, the Company reverted to its former name, Vodafone Group plc.

On 17 December 2001, Vodafone introduced the concept of "Partner Networks", by signing TDC Mobil of Denmark. The new concept involved the introduction of Vodafone international services to the local market, without the need of investment by Vodafone. The concept would be used to extend the Vodafone brand and services into markets where it does not have stakes in local operators. Vodafone services would be marketed under the dual-brand scheme, where the Vodafone brand is added at the end of the local brand. (i.e., TDC Mobil-Vodafone etc.)

On 18 June 2012, Cable & Wireless' shareholders voted in favour of the Vodafone offer, exceeding the 75% of shares necessary for the deal to go ahead.

On 2 September 2013, Vodafone announced it would be selling its 45% stake in Verizon Wireless to Verizon Communications for $US130 billion, in one of the biggest deals in corporate history.

On 9 October 2008, the company offered to acquire an additional 15 per cent stake in Vodacom Group from Telkom. The finalised details of the agreement were announced on 6 November 2008. The agreement called for Telkom to sell 15 per cent of its 50 per cent stake in Vodacom to the group, and demerge the other 35 per cent to its shareholder. Meanwhile, Vodafone has agreed to make Vodacom its exclusive sub-Saharan Africa investment vehicle, as well as continuing to maintain the visibility of the Vodacom brand. The transaction closed in May/June 2009.

In August 2013, Vodafone has started the MVNO operation in Brazil, as a corporative M2M operator.

In the United States, Vodafone previously owned 45% of Verizon Wireless in a joint venture with Verizon Communications, the country's largest mobile carrier. Vodafone branding was not used, however, as the CDMA network was not compatible with the GSM 900/1800 MHz standard used by Vodafone's other networks and as Vodafone did not have management control over Verizon Wireless. On 2 September 2013 Vodafone announced the sale of its stake to Verizon Communications for around $130 billion.

During the SMS for Life pilot, which covered 129 health facilities over six months, stock-outs dropped from 26% to 0.8%, saving thousands of lives.

The Vodafone Foundation is a recognised charity which supports and initiates projects which use mobile technology to benefit the vulnerable, using the slogan "Connecting for Good". They often work in collaboration with other charitable groups. Below are some examples of their initiatives:

Sir Gerald Whent, at that time an Executive with Racal Electronics plc, was responsible for the bid for a UK Cellular Network licence. The Mobile Telecoms division was de-merged, and was floated on the London Stock Exchange in October 1988 and Sir Gerald became Chief Executive of Racal Telecom plc. Over the next few years the company grew to become the UK's Market Leader, changing its name to Vodafone Group plc in the process.

Sir Christopher Gent took over as Chief Executive in January 1997, after Sir Gerald's retirement. Gent was responsible for transforming Vodafone from a small UK operator into the global operator, through the merger with the American AirTouch and the takeover of Germany's Mannesmann.

Arun Sarin was the driving force behind the Company's move into emerging markets such as Asia and Africa, through the purchases such as that of Turkish operator Telsim, and a majority stake in Hutchison Essar in India.

The fourth CEO, Vittorio Colao, stepped up from Deputy Chief Executive in July 2008.

Vodafone reports its results in accordance with International Financial Reporting Standards (IFRS). Financial performance has been as follows:

*Losses for year to 31 March 2006 reflect write downs of assets, principally in relation to the Mannesmann acquisition. Proportionate turnover includes £7,100 million from discontinued operations.

In September 2010, an investigation by Private Eye magazine revealed certain details of Vodafone's tax avoidance activities. It was reported that Vodafone routed the acquisition of Mannesmann through a Luxembourg subsidiary, set up to avoid paying tax on the deal, and continued to place its profits in Luxembourg. Following a long legal struggle with HMRC (during which a senior HMRC official, John Connors, switched sides to become head of tax at Vodafone), it was eventually agreed that Vodafone would pay £1.25 billion related to the acquisition. Based on Vodafone's accounts, experts have estimated the potential tax bill written off as a result of the negotiations was over £6 billion.

The news of this legal tax avoidance sparked angry protests, beginning in October 2010 and ongoing as of April 2011, outside Vodafone shops across the UK, organised under the banner of UK Uncut. The first protests caused the simultaneous closure of over a dozen stores, including the flagship Oxford Street branch.

In 2011, Private Eye magazine and The Bureau of Investigative Journalism alleged that Vodafone's Swiss branches were run by a single part-time bookkeeper. The report claimed hardly any business was done from there, indicating that the main purpose of the Zug office was tax avoidance. The report claimed the money was borrowed from the Swiss branch of the Luxembourg company, allowing it to take advantage of Luxembourg's laws, which exempts foreign branches of companies from tax, and Swiss laws, which almost completely exempt local branches of foreign companies. According to the expose, this would have otherwise generated a British tax bill on a little over £2 billion. It said Vodafone publishes a single, combined set of accounts for its Luxembourg subsidiaries and their Swiss branches. For the one company, profits worth £1.6 billion were taxed at less than 1% in 2011, and the profits are likely to have been attributed to Switzerland. In its response to these allegations, Vodafone has said the Swiss branch has not been involved in Vodafone's global financing for a number of years. It is, therefore, irrelevant in respect to global financing arrangements.

Vodafone was also assessed a US$2.5 billion tax over its acquisition of Hutchison Whampoa's Indian assets in 2007, a demand that it contests. In January 2012, the highest Indian court ruled that Vodafone is not liable for taxes and penalties of up to £2.8 billion. However, in February 2016 India's tax department sent Vodafone a renewed tax notice of £1.4bn. Following the siding of the Indian court with Vodafone in 2012, the government changed the law to allow firms to be retrospectively taxed.

Vodafone was implicated in the violent suppression of pro-democracy protests in Egypt's 2011 demonstrations. On 27 January, Vodafone, responsible for much of Egypt's telecommunication infrastructure, shut off all voice and data services for Egyptian citizens and businesses at the request of the Egyptian Government under Hosni Mubarak. On 28 January 2011, Vodafone complied with Egyptian government instructions to suspend Internet service "in selected areas" during a period of anti-Mubarak protests. The company issued a statement that "Under Egyptian legislation, the authorities have the right to issue such an order and we are obliged to comply with it." Vodafone also received public and media criticism for allowing the authorities to send mass pro-government messages via SMS over their network during the protests. One such message requested that "honest and loyal men" should "confront the traitors and criminals". Vodafone later issued a statement asserting that they had no choice but to allow the messages to be broadcast, and that they had complained to the Egyptian authorities about the practice. The Daily Telegraph of the UK reported, "The Egyptian government's action is unprecedented in the history of the internet." US-based Internet intelligence firm Renesys stated, "in an action unprecedented in Internet history, the Egyptian government appears to have ordered service providers to shut down all international connections to the Internet." Vodafone Group CEO Vittorio Colao said the company was obliged by law to comply with the instructions of the Egyptian government. At the company's annual general meeting, on 26 June, the campaign groups Access and FairPensions asked Vodafone to endorse a plan to prevent the company facing similar demands in the future.

In Australia, particularly towards the end of 2010, Vodafone have been heavily criticised due to allegations of poor customer service and severe technical inadequacies, which earned them their nickname "Vodafail" – a website of the same name still exists. In response, they have developed a "new" network, and now provide a 30-day satisfaction guarantee.

Vodafone UK, in common with other operators, has been criticised for holding customers on regular monthly billed contracts liable for almost unlimited roaming costs when their phones are stolen abroad, despite being seemingly able to limit costs of pay-as-you-go contracts.

In October 2016, Vodafone was fined a record £4.6m by Ofcom for "serious" breaches of consumer protection rules. In April 2017, Vodafone continued to have major issues with customer service, with the CEO Nick Jeffery inviting customers with unresolved complaints to email him directly.

In June 2014, Vodafone revealed information about theirs and other telecommunication operators' 'direct access systems', content data and metadata interception programmes globally.
