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.

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.

UK telecoms regulator Ofcom has just published its Connected Nations report, which shows how the UK’s communications infrastructure has changed in the past 12 months.

It notes that the roll-out of 4G coverage means that 67% of premises in the UK can now get 4G service from three of the ‘big four’ operators. That compares with 37% in 2014.

UK communications regulator Ofcom has decided that the annual mobile fees for mobile operators will treble, following a government direction that the fees should reflect ‘full market value’.

Ofcom has concluded that mobile operators should pay a combined annual total of £199.6m per year for the 900MHz and 1800MHz spectrum bands.

EE has committed to investing £1.5 billion on its network by the end of 2017 as part of a new manifesto called ‘Signalling the Future’.

It’s promising to deliver voice and 4G data coverage across 90% of the UK’s geography, which would exceed its current 2G footprint.

The adage that “the customer is always right” has apparently been disproved by a recent survey of mobile phone users.

Mobile News reports that virtual networks Virgin Mobile and Tesco Mobile outperformed their network partners in a recent customer satisfaction survey carried out by research firm YouGov for price comparison website uSwitch.

I knew I’d seen it before. Towards the end of last week I read about a study from the Department of Computer and Information Science at the University of Pennsylvania that said it was pretty easy to identify passwords from smudges on touchscreen mobile phones.

Yesterday I received the following text message from O2: “You’ve gone over your data allowance on your mobile. You need to cut down or get a bigger Bolt On to keep using the internet.” I thought this was strange as I’ve an unlimited data bolt on applied to my O2 UK contract so I decided to telephone O2 customer services to find out a little bit more. Here’s what happened.

This week's Carnival of the Mobilists – the best mobile blogging (and podcasting!) of the last seven days – is online at Tam Hanna's new TamsBada site. As always, you'll find a wide variety of mobile-related subjects and discussions.

Supermarkets. You either love ‘em or hate ‘em. Actually, that’s not true. Most of us seem to be happy enough with a half-price bottle of wine but less convinced about globalisation and supplier relationships.

But none of that’s bothering me today. Instead, I’m troubled – as I have been for several months – by the TV commercial for Tesco’s prepay mobile phone tariff.

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.
