We started this week with a story that grabbed plenty of attention. It was a report from Billmonitor.com that claimed we in the UK were wasting almost £5 billion every year by choosing the wrong mobile tariffs. Although I remained a little cynical about some of the detail, there's no doubt that many consumers could be better off if they switched tariff - or even network.

Oh, those nasty mobile networks. They're robbing us blind… at least, that's what you might think if you've been reading the headlines this week.

Mobile users 'overpaying by £200', said the BBC. £5bn 'wasted' on mobile phone bills, said the Financial Times. It's the wrong tariff, Gromit!, said Telecom TV after hitting the Wensleydale.

In this week's edition of The Fonecast we're chatting to David Emm, senior security researcher at Kaspersky Lab UK, about the security threats facing mobile phone users.

We also discuss the latest report from mobile tariff comparison site Billmonitor, we talk about Tuesday's Symbian news, we look at a new unlimited internet deal and we discover a clutch of MVNOs.

The Billmonitor.com price comparison website says over three-quarters of UK mobile phone customers are on the wrong mobile tariffs, which is costing those people almost £5 million annually. It's analysed over 28,000 mobile phone bills and has compared than against over 8.5 million tariff options from O2, Orange, Vodafone and T-Mobile.

Billmonitor's calculations show that those 76% of UK mobile customers on the wrong tariffs are wasting an average of £194.71 each per year.

We head into the weekend with the News of the World admitting voicemail hacking was more widespread than previously thought. Mobile networks had already made it much harder to access voicemail remotely… and now the NotW is saying sorry and preparing to pay compensation.

Mark Windle, head of marketing at OpenCloud, predicts that this year’s reduction in the number of traditional telecoms operators in some countries will provide an opportunity for other operators to innovate and capture market share in 2016.

He says next year will be a year of rapid change for telecoms… whether it’s MVNO disruption, competitive tariff pricing or simply defence from the ‘dark art’ of hacking.

The most memorable moments in life often go unrecorded. You don't have your camera in your hands. Your finger is still hovering over the 'pause' button on your audio recorder. Or you were simply too busy experiencing whatever was happening. It's all about the one that got away.

That's where Kapture can help.

James Rosewell shows me a colourful roll of paper that's the width of an iPhone but well over three metres long. When I look closer, I can see it's a printed copy of the Wall Street Journal's mobile website. That's a lot of scrolling to do... and a pretty unfriendly user experience for anyone reading the news online. Why does it work so badly?

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.
