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.

Apple is planning updates to its iOS and iPadOS mobile operating systems that will help prevent the spread of Child Sexual Abuse Material.

The Telephone Preference Service and Ofcom have introduced a new text message service that lets UK mobile users opt out of receiving unsolicited sales and marketing calls.

Mobile phone users can simply text ‘TPS’ and their email address to 78070.

Sajid Javid MP, the UK Government Secretary of State for Culture, Media and Sport, has announced what’s described as a “landmark deal” with the ‘big four’ mobile networks to improve coverage.

It follows a three-week consultation period that involved the government proposing mandated ‘national roaming’ as one of the options to improve rural coverage in areas where some networks provided service but others didn’t.

It's time for another news-packed mobile industry podcast from TheFonecast.com, starting with the European Parliament's latest ruling on in-car emergency communication.

After that we're talking about Microsoft's departure from the Nook eBook business, Three UK's 4G growth, Acer's tablet-sized phone, EE's rural coverage solution and some interesting new research about mobile-enabled customer service.

At the beginning of the 21st century I moved from Vodafone to work for its Vizzavi multimedia portal, wooed by talk of context-specific advertising that would one day use a customer’s location and search history to ensure any ads were precisely targeted. And I’m not the only person who’s been seduced. Consumers, ad agencies, client companies and mobile networks have all been promised much by mobile marketing.

Yet more than a decade later that kind of sophistication seems to be lacking from most mobile marketing messages.

This week there was only one set of financial results that attracted the mainstream tech media. Apple reported the first drop in quarterly profit for several years as figures fell by 18% to around £6.1 billion. On the positive side, it made around £6.1 billion profit. It also announced dates for its developer conference in June and promised a new version of iOS.

Due to growth in staff numbers my business (51Degrees.mobi) is in the process of moving offices. Coincidentally I'm also moving our home broadband. It’s not been a pleasant experience.

This got me thinking, because a few weeks ago on thefonecast.com we discussed why Ofcom isn’t treating Mobile Termination Rates (MTR) in the same way as fixed-line termination rates. The mobile industry justifies higher MTRs on the assumption that a mobile network costs more to run than a fixed-line network. It was certainly true when the fixed costs of running a mobile network had to be shared across a relatively small number of customers, even if they did pay a fortune for their contracts and terminals. Intuitively I'd say that’s just not true anymore.

The past few days have seen the arrival of two familiar seasons. Not only has the sun peeked its head from behind the clouds in an approximation of Spring but the mobile industry has been releasing its quarterly results.

It’s claimed there’s recently been some dodgy equine activity in the mobile industry. No, I’m not talking about the dancing pony that promoted Three UK. I’m not even making lasagne jokes. I’m talking about the ‘Trojan horse’ threatening to monopolise the mobile marketplace.

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.
