A new UK virtual mobile network is promising to give 25% of its profits to charity.

The People’s Operator (TPO) has set up a separate organisation - the TPO Foundation - that receives 25% of its profits and passes them on to good causes. In addition, customers can ask the TPO Foundation to give 10% of their individual monthly spend directly to a different charitable organisation of their choice.

Everything Everywhere has started offering a version of its ‘Orange Shots’ service to T-Mobile UK customers.

The new service will be called ‘You Choose’. Customers who choose to participate are asked about their interests and then receive tailored news, information and offers from relevant brands.

Mobile media company Blyk, which ran a virtual network in the UK until 2009, has announced that co-founder Antti Őhrling is leaving “to explore new emerging opportunities”.

Mr Őhrling was also chairman of Blyk India.

Mobile media company Blyk says Chief Commercial Officer Eric Kip has been appointed as Chief Executive Officer.

Blyk co-founder Pekka Ala-Pietilä, who’s stepping down after five years of running the business, will continue as the company’s chairman.

In this week's edition of The Fonecast we're returning to the subject of location-tracking on iPhones. We then move on to Nokia’s reorganisation, Visa's investment in mobile payment start-up Square... and RIM's plans for BlackBerry.

We also prepare for our forthcoming 250th podcast by turning the clock back to 2008, when we spoke to virtual mobile network Blyk about its first 100,000 UK customers.

A suggestion that UK mobile phone networks might be forced to improve black-spot coverage by allowing interconnection with their rivals is back in the news. It made the headlines in June and has returned again this week, which is why I could be heard offering my opinion on BBC local radio yesterday morning.

If I'm interviewing someone for a podcast, I'll generally use my Zoom H4N recorder and a separate microphone or two. But I don't need the same level of high-quality kit if I'm interviewing someone for a written interview. Why carry an expensive recording device when your mobile phone can do the same job?

Contactless payments. They're catching on, aren't they?

But mobile contactless payments haven't proved so popular.

I open the iPhone 6 box and discover a phone that feels substantial. Well engineered. Practical. Despite being just 6.9mm deep, it doesn't seem unreasonably delicate.

Following my online rant about the customer service I'd received when I suffered a problem with my HTC One, I wrote to Carphone Warehouse.

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.
