Two of the world's communications giants have agreed to merge their UK operations. Liberty Global will combine its Virgin Media UK broadband network with Telefonica's O2 UK mobile business.

In October, Ofcom revealed more information about its plans to auction the 2.3GHz and 3.4GHz radio spectrum it had received from the Ministry of Defence.

It planned to start the auction process in December 2015 but is now delaying this until 2016.

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.

Hong Kong-based Hutchison Whampoa Limited has published unaudited financial results for the first half of 2013.

The company, which has assets including port operations and mobile phone networks, reported profit up 23% year-on-year to HK$12.4 billion (£1.05 billion) for the six-month period.

Network operator Telefónica has agreed to sell its Telefónica Ireland business, which trades as O2, to the Three subsidiary of Hutchison Whampoa.

The deal is worth €850 million (£722 million), with €780 million paid when the deal is completed and a further €70 million paid if financial targets are met.

I've been taking a look back at the devices I've written about during the past few years. Some are still faithful companions, others... well, let's just say my faith was misplaced.

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.

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?
