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.

Mobile networks have changed, haven’t they?

Once they were all about delivering service. Coverage. Quality. Price. Now it’s much more about branding.

Everything Everywhere has announced it’s to become EE, an obvious abbreviation that’s been used in mobile industry briefings pretty much since the company was created two years ago. It joins the likes of Kentucky Fried Chicken, Hennes & Mauritz, British Home Stores, Independent Television and Marks & Spencer, although all of these took decades to transition into businesses that were just described by their initials.

Mark Bridge writes:

It’s a smartphone autumn, as prophesied a few weeks ago by the Carphone Warehouse and many others. The frenzy of big-name announcements led by Samsung at Berlin’s IFA has given way to stand-alone media presentations from Nokia, Motorola and Amazon.

Ted Landphair of voanews.com writes:

A lot of people gave up carrying much cash a long time ago, since they knew ‘plastic’ - a credit or debit card, or a store or public transit ‘smart card’ - would be accepted just about everywhere.

But to hear tech companies tell it, plastic cards will be museum pieces as well before long.

Mark Bridge writes:

It was a week of dramatic contrasts in the mobile phone industry. We started with Everything Everywhere’s news that 4G service was coming to the UK this year – possibly with a new brand that’ll work alongside Orange and T-Mobile. Meanwhile Three UK seems to have its own plans that involve acquiring some excess 4G spectrum from Everything Everywhere. There was much muttering from Vodafone and O2, although whether this’ll manifest itself as legal action remains to be seen.

Robin Kent writes:

With this week’s announcement that Everything Everywhere has been given the green light to launch the UK’s first 4G service, competing operators such as Vodafone and O2 are getting hot under the collar. With every day that goes by, these operators lose vital competitiveness as the market creeps away them towards Orange and T-Mobile. This is a real life ‘hare and tortoise’ scenario.

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.
