TAKING THE PULSE: European telecom companies are expected to report a spike in data revenue due to the rising popularity of smartphones and tablets, but landline operations will remain sluggish.

The performance of the world's biggest mobile operator, Vodafone Group PLC (VOD), will come under scrutiny Thursday given the U.K.-based group's extensive operations, particularly in Europe.

Many analysts expect France Telecom to underperform the telecom sector in 2011 due to the tough competitive environment in France, with Exane BNP Paribas preferring Deutsche Telekom AG (DT) and BT Group PLC (BT.A.LN) among the European incumbents.

COMPANIES TO WATCH:

---Vodafone Group PLC (VOD) 3Q results--- (Feb. 3)

MARKET EXPECTATIONS: Vodafone is expected to report a 1.9% rise in group service revenue--one of the key figures tracked by U.K. analysts--to GBP10.9 billion for the fiscal third quarter from GBP10.7 billion a year earlier. The mobile giant may also name a new chairman following heightened speculation that Chairman John Bond is leaving.

MAIN FOCUS: Investors and analysts are anxious to hear about current trading conditions, and the expected sale of its 44% stake in French telecom operator SFR to partner Vivendi SA (VIV.FR). Any comments on the situation with its partners in the U.S. and India will also be closely watched.

---BT Group PLC (BT.A.LN) 3Q and 9 month results--- (Feb. 3)

MARKET EXPECTATIONS: BT is expected to report a 3.2% fall in revenue to GBP5.03 billion in the fiscal third quarter from a restated GBP5.20 billion a year earlier as customers use their landlines less in favor of mobile phones. But analysts forecast a 4.9% rise in adjusted Ebitda to GBP1.45 billion from a restated GBP1.39 billion due to further cost cutting. BT restated its fiscal 2010 numbers as it changed the way customer accounts were treated in its BT Retail and BT Wholesale divisions, effective from April 1 2010.

MAIN FOCUS: The market will be looking for an update on the group's broadband customer numbers, after rival British Sky Broadcasting Group PLC (BSY.LN) reported higher-than-expected take-up, as well as details on the group's cash flow position.

France Telecom SA (FTE) 4Q and FY results --- Feb. 24

MARKET EXPECTATIONS: France Telecom's fourth-quarter results are expected to have benefited from a continued improvement in domestic sales after the group repositioned its offers and prices in the summer. France Telecom raised its full-year guidance in October, saying it expected full-year revenue to grow slightly compared with last year, excluding the hit from recent regulatory measures, notably due to the improvement in France, its largest market. However, analysts say competition in France has intensified over the last quarter and the competitive environment is expected to be even tougher in 2011, which is likely to be a drag on 2011 earnings.

MAIN FOCUS: France will be the key focus for analysts, which will closely eye management comments on recent developments in the market. Exane BNP Paribas estimates earnings before interest, taxes, depreciation and amortization in France to decline by more than EUR600 million, or 7%, in 2011 amid increasing competition in the broadband market as well as increasing pricing pressure in mobile. Analysts also say the recent hike in value added tax could lead to higher churn and commercial costs in the first half of 2011.

---Telecom Italia (TI) 4Q and FY results--- (Feb 24)

MARKET EXPECTATIONS: Analysts expect a tricky top line in 4Q, but strong savings with signs of debt reduction in 2010. Service revenue is expected to fall a further 8% in the fourth quarter, despite an easier comparison. However, domestic savings and growth in Brazil are expected to stay strong in line with full-year guidance. Analysts also note that a realistic industrial plan is needed to show management understands problems and can manage competition.

MAIN FOCUS: The market focus will remain on the domestic operations' performance and the trends reported in the division, as well as the outlook for 2011.

---Deutsche Telekom AG (DT) 4Q and FY results---(Feb. 25)

MARKET EXPECTATIONS: Deutsche Telekom's management reconfirmed in recent weeks that Germany's incumbent telecom provider has achieved its 2010 target of adjusted earnings before interest, taxes, depreciation and amortization of around EUR19.5 billion and free cash flow of at least EUR6.2 billion, hence analysts see no major surprises and the declared dividend policy is not at risk. The drastic cut in German mobile termination rates, which came into effect Dec. 1 will likely weigh on the results and Germany's fixed line revenue is seen down. Some analysts think Deutsche Telekom may have scaled down marketing activities in order to hit the prior year's targets.

MAIN FOCUS: The main concern will be the turnaround of Deutsche Telekom's U.S. operations which has been under investor scrutiny for the last two years. That is despite T-Mobile USA's investor day on Jan. 20 where not all analysts were convinced by the turnaround plan that was presented.

--- Telefonica SA (TEF) 4Q and FY results --- (Feb. 25)

MARKET EXPECTATIONS: Telefonica earnings should remain on solid footing, as strength in Latin America offsets weakness in European markets, particularly crisis-hit Spain. Brazil's Vivo-- which is likely to be fully consolidated in the quarter for the first time--and Telesp may remain as the company's top success stories, while Mexico is still a bit of a laggard. The U.K.'s O2 may also be a reason for optimism, as the launch of the iPhone 4 boosts sales and network usage.

MAIN FOCUS: Telefonica's capital expenditure is likely to be in focus, as it normally picks up in the second half of the year. Spanish 4G rollout still appears distant, but the company is expected to talk up growth opportunities in Brazil after the Vivo purchase late last year left it in a solid position to benefit from the booming economy and higher consumption. Any comments on dividends and shareholder returns may be in focus, as Chairman Alierta has already warned that the M&A era may have been left behind as the company's footprint looks sufficient to maintain its dominant position in target markets.
