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.

Another week, another couple of product announcements from Samsung. There appears to be no stopping them, despite a recent drop in the company’s share price.

This time it’s a couple of tablets – one of which runs both Android and Windows 8 – and a 20 megapixel camera that’s got a 4G-enabled Android device built in.

The telecommunications industry was making plenty of headlines last week – but much of it wasn’t particularly upbeat.

The debate about privacy and security continued in the wake of allegations about US agents intercepting internet traffic. Meanwhile, Nokia prepared to make its last Symbian smartphones and Tradedoubler warned that mobile devices were having a negative effect on high-street consumer loyalty.

When news broke about U.S. government agencies collecting metadata about its citizens’ Internet and phone communications, many were surprised by its scope. The surveillance covered a vast number of Internet messages and phone calls. The government did not deny the action but pointed out that the collected data contained, not the substance of the communication, but the so-called metadata.

There’s been a lot of talk recently about PRISM, which may allow the US National Security Agency - and anyone they choose - to access some of our personal online information if it passes through the USA. It’s unclear exactly what (if anything) is being shared with whom… and given the nature of national security, we may never know.

However, alongside the possibility of governments seeing information we thought was secure, it’s also worth pointing out that we choose to share plenty of online information ourselves.

Where did it all go wrong?  When did the mainstream mobile industry start to slide away from innovation and into repetitive nonsense?  For a while I suspected the downloadable ringtone was to blame. Just days after hearing 'Barbie Girl' on the mobile phone of a man from Vodafone Value Added Services in the late 1990s, I'd downloaded a poptastic tune to my own Nokia 2110. Soon, the entire mobile world was focussed on 30-second instrumentals instead of technical innovation. It was the beginning of the end.

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.
