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.

UK communications regulator Ofcom has fined O2 £150,000 for failing to provide accurate and complete information during an investigation. It follows a £10.5 million fine for the network earlier this year.

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.

Entertainment company Sky has announced what it’s calling “the UK's most flexible mobile service”.

Customers with another Sky service will be able to sign up for Sky Mobile from mid-December, with a full launch expected in early 2017.

Persuading mobile phone users not to hold their phone when they’re driving should be a simple task. It’s dangerous, it’s against the law and the penalties include a fine plus points on your licence.

But even then, there’s often an excuse about convenience and usability. Some people don’t like wearing headsets, some don’t like wires and some simply forget to charge the batteries.

That’s why a new hands-free Bluetooth loudspeaker from French company BeeWi caught my eye.

I remember the launch of Carweek back in the 1990s. It was a motoring magazine produced as a weekly glossy newspaper; a novel format, although one that probably led to its demise. 'Spy shots' of prototype cars seemed then – as now – to be much sought-after, despite them often not showing much resemblance to the finished product. Indeed, I often wondered how you could possibly road-test the handling of a new car when it was covered with unflattering body parts that served to disguise its shape.

'Unboxing' is - or was - the new geek porn. We know this because The Register told us so in 2006, when the practice of video recording the unpacking of new consumer electronics products started to become popular. Just over two years later The Independent tried to tell us that unboxing was still the new geek porn but, by then, conventional porn had probably returned to... er... pole position.

Why do I mention this?  Well, Sony Ericsson has just published its own unboxing video featuring tennis player, model, charity worker and Sony Ericsson brand ambassador Maria Sharapova.

Last week I spotted a couple of mobile-related news stories that involved payment company MasterCard. One came from CPI Card Group, which had introduced a “next-generation, MasterCard-approved payment tag” (a.k.a. 'sticker') that enabled “any mobile device to be used to make payments anywhere using the worldwide contactless MasterCard PayPass standard” (by sticking it on the back).

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.
