LONDON-- BT Group PLC on Monday said it is in talks to buy Telefónica SA's U.K. mobile business, 02, as the British telecom incumbent lays out its ambitions to be a fully-fledged wireless operator in the U.K.'s converging telecom market.

BT is already planning a return to consumer mobile next year, but said it is exploring ways of "accelerating" its plans, which includes assessing the merits of an acquisition of a mobile network operator in the U.K.

The 168-year-old London-based group, responding to recent media reports, said it had received "expressions of interest" from shareholders in two U.K. mobile network operators, of which one is O2, about a possible transaction in which BT would acquire its U.K. mobile business. Analysts value 02 at around $14 billion.

O2, with more than 23 million customers, is the second-largest U.K. wireless operator behind EE--a joint venture between Orange SA and Deutsche Telekom AG--and ahead of Vodafone Group PLC and Hutchison Whampoa Ltd.'s Three.

The other U.K. network operator being offered to BT is EE, according to a person familiar with the matter, which would bring together the U.K.'s biggest fixed-line operator and largest mobile operator. EE declined to comment. Orange and Deutsche Telekom weren't available for comment.

"All discussions [with Telefónica] are at a highly preliminary stage and there can be no certainty that any transaction will occur," BT said in a statement.

BT confirmed the talks after a report in the Spanish media said Telefónica is negotiating taking a 20% stake in BT in exchange for O2. BT wasn't available for further comment.

Telefónica also confirmed the talks, saying they were at a "very preliminary phase."

A deal for O2 would see BT reacquire a wireless business it demerged in 2001, called BT Cellnet. Telefónica bought O2 in 2005 for GBP17.7 billion ($27.7 billion).

Earlier this month, O2 said total mobile customers increased 3% year-over-year to 24.1 million at the end of September 2014. Third-quarter revenue, excluding the impact of the operator's tariff plan that splits out device and service costs, rose 2.3% year-over-year to GBP1.43 billion.

In early afternoon London trading, BT shares rose 2.7% to 390.1 pence in a lower market. Telefónica shares were up 0.9% at EUR12.59.

Citi analyst Simon Weeden said BT would need cost savings to make any deal profitable because of the U.K. mobile sector's low margins, adding that extra funding might be required. "We would not rule out a capital increase at BT to pay for an acquisition of this size," he said.

"A sale would allow Telefónica to focus more resources on markets where it has a competitive advantage, such as Brazil, Colombia, Mexico and Germany," said Javier Borrachero at Kepler Cheuvreux. Mr. Borrachero added the group is better off leaving the U.K. market during the current deal-making wave than trying to bulk up.

Telefónica has already reshuffled its businesses in Germany and Brazil, becoming a leading player there. In Germany, it spent EUR8.1 billion ($10.6 billion) last year on E-Plus, a mobile carrier previously owned by KPN NV. And earlier this year in Brazil, it paid EUR7.24 billion for Vivendi SA's GVT. Over the same period, the Madrid-based company sold units in the Czech Republic and Ireland that lacked sufficient scale.

BT offers retail consumers so-called triple-play services of fixed phone, Internet broadband and television, and competes for subscribers with rivals such as Liberty Global PLC's cable operator Virgin Media and pay-TV giant Sky PLC. It has invested billions of dollars into sports channels and recently signed a partnership with U.S. streaming platform Netflix Inc. to lever up its premium fiber services. Next year, through a leasing deal with EE's network, it plans to launch a consumer mobile offer to supplement its existing business service.

Last week, senior executives from the parent companies of both O2 and EE cast doubt on their futures.

Telefónica said it would consider all strategic choices for its U.K. operations, including a possible sale, should Britain's telecom operators continue to add fixed-line assets and television content to their wireless services.

"If the U.K. is to be a convergent market, then we need to evaluate all possibilities," said Telefónica's Chief Operating Officer José María Álvarez-Pallete, speaking at the Morgan Stanley telecom, media and technology conference in Barcelona.

And Orange Chief Executive Stéphane Richard said the 50-50 EE mobile venture isn't a long-term plan, adding that "all options are open" including a public listing or merger and acquisition deal.

"This could be the moment that commitment to the U.K. mobile market finally cracks and we see parent companies starting to exit," said Citi's Mr. Weeden. "BT is unusual, if not globally unique, in being a fixed-line incumbent without its own mobile network operator."

Unlike countries such as Spain and Germany, U.K. telecom operators have yet to fully embrace so-called quadruple play offers of fixed telephony, mobile, broadband Internet and television. But rivals Vodafone and EE are moving into the space. Virgin Media and telecom group TalkTalk also participate in "quad" play.

European telecom operators are eager to move into broadband and media services outside their core telephony business to jump-start flagging revenues across the continent's anemic wireless markets. Bundled services are also perceived to boost subscriber revenue and increasing customer loyalty.

Bold market moves are buoyed by favorable sentiment, says Barclays analyst Maurice Patrick. "Following years of relentless earnings pressure driven by macro, competition, regulation and technology, we believe the tide is finally turning positive."

Still, despite improving trends, analysts say BT's moves may be partly forced by moves by rivals and the risk of being left behind.

"Defensively, BT has [mobile] covered through the [EE mobile virtual network deal] anyway. It would be a strange decision to do this because of quad-play," said Enders Analysis analyst James Barford. "Part of the justification is likely to be an ability to cross-sell products."

BT has invested GBP200 million in radio spectrum at the higher end of the cellular range, analysts say, with the frequencies suitable for short-ranged, high speed mobile that use the fastest fourth-generation wireless technology, otherwise known as "long-term evolution," that is booming data revenues for telecoms in Europe.

Marketing decision-making is also key, added Mr. Barford.

"The issue BT had was that its brand isn't very appealing towards younger people," he said. "There is a risk that if it rebranded [the mobile service as] BT that wouldn't be appealing to a significant part of the O2 base. With EE, there isn't such an issue."
