A new iOS and Android app called Sidecar promises to enhance mobile and WiFi voice calling with additional ‘smart calling’ features. Users can offer video, photo sharing and location information during a voice call.

An additional benefit is the ability to call any mobile telephone number in the US and Canada for free when using WiFi, even if the recipient isn’t using Sidecar.

Microsoft has released the ‘Gold Version’ of Skype for Windows Phone, marking the end of the product’s beta period.

The beta version was launched during Mobile World Congress in February.

VoIP and video calling service Skype is now available for Windows Phone devices.

A beta version of the WP7 app is available now, with the finished ‘gold’ version due in April.

ABI Research says mobile video usage is expected to grow dramatically during the next five years - but it won’t become the ‘new voice’.

Video telephony, video sharing and video messaging services over mobile networks were used by less than 47 million consumers at the end of last year. However, usage is expected to grow eight-fold to reach 390 million users in 2016.

Google has augmented its Google Talk instant messaging app to include video and voice chat for Android phones.

The new service enables consumers to make video calls over 3G or WiFi between phones or from a phone to a PC. Text chat from the person you're talking to will appear in front of the video on your phone's screen.

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?

We start this week's show with news about the European Commission's plans to end mobile roaming charges completely from next year.

We're also talking about the future facing Twitter and Dell, Vodafone's security challenges in Germany, app development, wireless charging, mobile payments and Nokia's Android-based smartphones.

This week's show is packed with new products, including two iPhones, three smartwatches, two Android smartphones and a couple of innovative lens-based camera accessories.

We also find time to talk about mobile security, virtual networks and being dishonest via text message.

We're back after a short break last week - and just in time for three of the biggest industry news stories of the year.

Microsoft's CEO announces his retirement, then Vodafone sells its US operation for $130 billion... and now Nokia's mobile phone business is being bought. Alongside these reports there's also time to talk about 4G in the UK, children with mobiles, roaming charges and the future of smartphones.

In this special feature we're talking to David Akka, who tells us why he says Android is dead, why Chromecast is an omen for the mobile industry, why OS companies are getting into hardware and what the future holds for the mobile industry.

David is UK managing director of Magic Software and describes himself as a 'recovering techie'. His personal blog is at davidakka.com.

There's good news for Telefonica as it's chosen to support the UK's smart meter rollout - but bad news for fans of the Microsoft Tag barcode, which is being discontinued in a couple of years' time.

We're also talking about drivers who use mobile phones illegally, Amazon's new service for mobile developers, the forthcoming Kazam smartphone, mobile advertising, satellite broadband, wearable security accessories and a word that's completely unacceptable to Motorola.
