It's Thank You and goodnight from Dido -- Dido Harding, current CEO of UK broadband provider TalkTalk , that is, who is stepping down from her role in May, to be succeeded by Tristia Harrison, currently managing director of TalkTalk's consumer division. Charles Dunstone, who himself is stepping down from his role as chairman of Dixons Carphone in May, will assume the role of executive chairman.

TalkTalk hit the headlines in 2015 for a massive security breach from which it took many months to recover. But while some media coverage is suggesting that incident might have been the catalyst for her departure, that doesn't appear to be the case: If every CEO quit because their company had been subject to a security breach then it would be good news only for headhunters -- and if she was being forced out because of TalkTalk's hack, that would surely have happened a long time ago, not 18 months after the fact. But when you are the CEO of a public company and the share price is down 24% compared to a year ago, then it seems your time is up. What is notable from Ofcom statistics, though, is that while TalkTalk still fails to achieve above-average scores in customer satisfaction ratings for fixed-line voice and broadband services (according to the Q3 2016 statistics), TalkTalk's customer satisfaction ratings have improved significantly during the past year, albeit from a pitifully poor starting point, so Harding has at least one feather in her cap as she leaves. the operator also published a trading statement today: In the three months to December 31, 2016, group revenues at TalkTalk fell 5.2% year-on-year to £435 million (US$549.4 million).

On Tuesday evening the EU parliament and Council negotiators finally agreed on wholesale roaming price caps. Apart from where they apply to SMS messages, the caps agreed are significantly lower than those proposed by the European Commission. They are as follows: €0.032 for voice call, instead of the proposed €0.04; a gradually decreasing cap, from €7.7 (6/15/2017) to €6 (1/01/2018), €4.5 (1/01/2019), €3.5 (1/01/2020), €3 (1/01/2021), €2.5 (1/01/2022) per gigabyte instead of €0.0085 per megabyte (or €8.5 per gigabyte); and €0.01 for text messages, as proposed by the Commission. But the talking's not over yet: the agreement still needs to be formally approved by the Industry Committee, Parliament as a whole and national ministers before coming into force. Whatever happens in those talks, mobile roaming charges for EU consumers will end on June 15. (See Eurobites: Dunroamin'.)

Finnish operator DNA Oy has called on Ericsson AB (Nasdaq: ERIC) to boost its mobile broadband offering in Finland's more sparsely populated areas. DNA is using the Ericsson Radio System for mobile broadband in the 700MHz spectrum. Maybe it's something to do with the weather, or the price of beer, but the Finnish population is thought to be the most active in the world when it comes to using mobile data.

As macabre mementos go, it's right up there: The Daily Mirror reports that a blood-red "mobile" phone used by Adolf Hitler throughout World War II is being put up for auction in Maryland, US, later this month. The Bakelite phone, which was found in Hitler's bunker by Russian troops at the end of the war, is expected to fetch £400,000 ($505,000) at auction. Interesting. Yet chilling.
