More second-quarter financials fun today, as Nokia Corp. (NYSE: NOK), Ericsson AB (Nasdaq: ERIC), Telenor Group (Nasdaq: TELN) and ADVA Optical Networking open up their books.

Nokia generated revenues of €9.28 billion (US$13.13 billion) in the second quarter of 2011, down 7.2 percent compared with a year ago. (See Nokia Reports Q2.)

Ericsson, the Swedish networking infrastructure giant, saw its second-quarter revenues grow 14 percent year-on-year to 54.8 billion Swedish kronor (US$8.55 billion), but its profits of SEK 3.2 billion ($499 million) -- which were hit by the cost of job cuts in Sweden, among other things -- disappointed investors. (See Ericsson's Growth Spurt Continues, Ericsson Reports Q2 , Ericsson's SPIT Vision and Ericsson Signals New M&A Era.)

Asian operations came to the rescue of Norway-based carrier Telenor in its second quarter, reports Reuters, with 21 percent organic revenue growth in the region helping to raise the overall figures clear of analysts' predictions.

Second-quarter revenues at ADVA, the German metro transport vendor, were up 13.4 percent year-on-year at €77.8 million ($110.3 million). ADVA cites network traffic growth driven by video applications and cloud computing services as one of the primary reasons for its continuing success.

Vodacom Pty. Ltd. , the South African mobile operator majority-owned by Vodafone Group plc (NYSE: VOD), reported an 8.1 percent year-on-year rise in second-quarter revenues, with demand for mobile data proving to be the real growth engine.

Telia Norge, a subsidiary of Swedish carrier Telia Company , has sold its shares in U.K.-Norway subsea cable system North Sea Communications AS (NSC) to HitecVision for approximately SEK 170 million ($26.3 million). The system serves the North Sea's oil and gas industry. (See TeliaSonera Sells North Sea Cable.)

U.K. regulator Ofcom has a passion for pumping out surveys, and its latest has found that customer satisfaction levels in the mobile arena are higher than they are in landline-land. The best-performing landline provider in the survey was Sky , with a 66 percent satisfaction rate, while T-Mobile (UK) topped the mobile operators' chart, with 72 percent of users giving it the thumbs-up. In the broadband space, Orange UK outperformed the other big names, surprisingly leaving Virgin Media Inc. (Nasdaq: VMED) -- which has achieved plaudits for its downlink speeds -- languishing in the next-to-bottom spot. (See Ofcom Samples Satisfaction Levels.)
