TalkTalk Group, which started life as part of Carphone Warehouse before demerging in 2010, has bought the Tesco broadband and fixed-line voice base from Tesco plc.

This gives it around 75,000 broadband customers and around 20,000 voice customers, which will be transferred to the TalkTalk network.

Time for another podcast presented by Iain Graham, James Rosewell and Mark Bridge. They begin this week's programme by talking about the latest enterprise-friendly developments from BlackBerry.

Next comes a new survey from Ofcom about the UK's 4G data speeds, followed by news about TalkTalk's MVNO deal with Telefonica, the growth of WiFi in the home and a report from AVG about social media sapping smartphone performance.

Telecoms business TalkTalk has set up a  new multi-year MVNO agreement with Telefónica UK, the company behind O2.

TalkTalk’s current virtual network agreement is with Vodafone.

Ofcom has published its latest quarterly report, which shows details of the amount of complaints it’s received about major telecoms and pay TV providers.

This new report covers the period from July to September 2013.

The UK government says it’s worked with telecoms companies to reduce the risk of consumers receiving unexpectedly high bills if their phone is stolen.

Culture Secretary Maria Miller has announced a new agreement with EE, Three, Virgin Media and Vodafone to cap bills on a mobile phone that has been reported lost or stolen.

Ah, the joys of multiplying by zero. I was reminded of my school maths lessons when I saw a news release from Orange UK this week.

Steve Wallage, Head of Sport Partnerships and Services for Orange UK was quoted as saying “Based on the surge in demand for mobile TV during the Ashes last summer, we expect viewing figures could rocket by at least 74% during the World Cup”.

I loved the film WarGames. I saw it in the cinema when it came out… and developed a minor crush on Ally Sheedy as a result. If you don’t remember the film – or haven’t seen it – the plot centres on a young computer hacker who almost starts World War III while playing an illicit online game of Global Thermonuclear War with a military computer.

It’s time to take sides. Are you with Apple… or are you against them?  Sorry, sitting on the fence is no longer acceptable. Not sure?  Okay, try this one for size. Are you with Google… or are you against them?  Still undecided?

Right – here’s your third choice. Are you with the Rebel Alliance?

It's not often that a news story about the Apple iPhone prompts me to remember a bible verse... but this week was an exception.

The story was in The Washington Post and it was headlined 'Apple's iPhone does well without being the best'. “Very true,” I thought, as I remembered something similar I'd written last summer.

Welcome to the Carnival of the Mobilists #224. If you’re a regular visitor to The Fonecast and have no idea what the Carnival is, this is a summary of the week’s best blogging about all things mobile. It travels the internet, alighting at a different mobile-related website every week.

Iain Graham, James Rosewell and Mark Bridge return to review their mobile industry predictions from last year. Which mergers, partnerships and developments did they forecast correctly... and which didn’t work out as planned?

Later in the programme, the team anticipates some of the topics that will be hitting the headlines during 2016.

Mark Bridge learns about the mobile technology trends at Mobile World Congress 2015 by chatting to James Rosewell of 51Degrees, Dr Kevin Curran from the IEEE and Chris Millington of Doro.

They talk about wearable devices, wireless charging, mobile operating systems and much more... including some of their favourite products from the exhibition.

We're taking a look back at the biggest mobile industry news stories from February 2015, including allegations that the UK's security service tried to breach SIM card security by hacking into one of the world's biggest SIM producers.

We also talk about the planned BT and EE merger, the creation of two new UK virtual networks, some acquisitions in the mobile payment arena and a new Ubuntu smartphone.

In today's programme Mark Bridge talks to Chris Millington, who's Managing Director for Doro UK and Ireland.

They discuss the state of mobile retailing in the UK, the future of wearable devices and - as you might expect - smartphones for seniors.

We're back with a month of mobile industry news, including takeover talks and takeover rumours. O2 and Three are said to be discussing a merger... but is there any truth in the suggestions that BlackBerry could be up for grabs?

We also discuss Apple's record-breaking quarterly figures, the highlights of CES and the launch of Microsoft Windows 10, as well as saying farewell to the current version of Google Glass.
