Vodafone Group plc and CK Hutchison Group Telecom Holdings Limited have agreed to combine their UK telecommunication businesses, respectively Vodafone UK and Three UK. The merger will create a large new network operator to compete with Virgin Media O2 and EE.

Mobile phone customers from the UK have been warned about the increasing cost of making calls in Europe.

The UK's post-Brexit trade deal with the EU opened the door for mobile operators to reintroduce 'roaming' charges when customers travel abroad.

Ofcom, the UK's communications regulator, has published its annual customer satisfaction ratings for mobile networks.

Two of the world's communications giants have agreed to merge their UK operations. Liberty Global will combine its Virgin Media UK broadband network with Telefonica's O2 UK mobile business.

The European Commission has blocked the proposed merger of Telefonica UK’s O2 network with Hutchison’s Three.

It said it was concerned that the deal would have harmed innovation, reduced consumer choice and caused prices to rise.

I like hotels. Free biscuits in your room and all the portions of UHT milk you can drink. But the phone calls... that's a different story.

Dearie me, you're paying for that hospitality tray when you pick up the phone.

A Charlie Chaplin DVD includes an image of a woman using a mobile phone in 1928.

That’s the suggestion surrounding a YouTube clip that’s currently received more than 2½ million hits since it was posted online last week.

Most Sat-Nav applications are now obtained via the Application Store used on the mobile phone. Navigon have gone so far as to remove access to their application via any other route. Application Stores are now the only choice. This move to a platform-specific sales model is a massive mistake.

Mark Zuckerberg's girlfriend breaks up with him acrimoniously. So off he goes and creates Facebook. Yes, there's nothing like an insult to fire up the creativity. Well, that's certainly what the plot of The Social Network would like you to think.

And, you know, it's got a point. In fact, I'd go as far as to say that sticking two fingers up at the opposition seems to be the new way of doing business.

Wouldn't it be great if mobile customers loved their networks so much that they'd fight for them?  Ofcom would be inundated with complaints from O2 users about its decision not to allow GSM frequencies to be used for 3G services. Vodafone customers would demand that Nokia pre-loaded the N8 with a Vodafone 360 application. Orange users would be sending petitions to radio stations, asking them to implement HD Voice on phone-ins. And giffgaff users would take to online forums to defend the service they receive.

Oh, hang on. That last one's already happening.

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.
