UK communications regulator Ofcom has published a report looking at the use of online communication services. The report reveals that WhatsApp is the most popular messaging app among UK adults, with 76% of respondents having used it in the past three months.

Wireless communications trade organisation CTIA-The Wireless Association has found that mobile data usage exceeded 1.1 trillion MB from July 2011 to June 2012, a 104% increase from the previous 12 months.

There are now 321.7 million mobile connections in the USA, the equivalent of 101% mobile penetration.

Juniper Research has forecast that the amount of mobile messaging traffic worldwide will reach 28.2 trillion messages per year by 2017, nearly double the 14.7 trillion messages expected to be sent this year.

It says most of this growth will come from instant messaging (IM), which will account for over a quarter of all mobile messages in five years’ time.

A couple of research reports this week have noted that text messaging and picture messaging growth is slowing down. Could this be the end for our trusty friend SMS and its bolder, brighter (and slightly flakier) sibling MMS?

HP, Facebook and Twitter are all up for discussion in The Fonecast this week, along with customer service complaints, mobile security failings and children with iPhones.

It’s the telecoms industry deal of the year. T-Mobile and Orange form a joint venture. The UK’s "big five" networks (or "big four", depending on your predilection for Hutchison 3G UK) will now be a "big four" (or "big three", if you don’t include 3. Confused yet?)

Everyone has an opinion. On Tuesday I was asked for mine.

Once upon a time, I’d probably have described myself as a feminist. These days I probably wouldn’t. Not because my opinions have changed, just because I’ve realised there are a lot of women who’d argue that I can’t be a feminist because of my male undercarriage. And me, by birth and possibly by education, therefore being part of the problem – not part of the solution.

Right, disclaimer over. I’ll get to the point. You want a mobile phone that’ll appeal to men...

Mobile phones fry your brain. That’s been a warning from some people pretty much since the first cellphones appeared. And although the mobile phone industry has changed and the technology has advanced, the warnings haven’t gone away.

Ten years ago, the Independent Expert Group on Mobile Phones was set up to look at concerns about the possible health effects from the use of mobile phones, base stations and transmitters.

Enthusiasm is one of the great intangible powers of the world. It’s attractive, it’s compelling and sometimes it’s dangerous. And – yes, I’m going to try to keep this relevant – it sells mobile phones.

I was reminded of this the other day when I read a Sunday Times article about Apple’s Steve Jobs.

Marketing, not unlike football, is a funny old game. I don’t claim to be an expert in either… but every so often something happens that starts sowing the seeds of doubt in my mind. And no, I’m not thinking about Liverpool's penalty claims in Sunday’s game at Tottenham. I’m thinking about Blyk.

Here at The Fonecast, we like Blyk. They shook up the industry and worried some of the big names when they arrived with their youth-focussed virtual mobile network two years ago. We interviewed their MD Shaun Gregory in May last year. And now they’re quitting the MVNO game in favour of arranging advertising deals for networks.

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.
