We begin this week's podcast with updates on two topics we discussed last week: the potential purchase of a UK mobile network by BT - and the crowd-funded Jolla Tablet.

After that we talk about the GSMA's reaction to national roaming, the potential death of the landline, a new threat to Google, management changes and advertising for 4G data.

The Advertising Standards Authority has upheld complaints about a promotional message from UK virtual network Lycamobile.

A link on Lycamobile’s web site referred to “Unlimited Data, now with 4G”, while an advertisement on the site said “£15 per month ... unlimited data now with 4G”.

International virtual mobile network Lycamobile has appointed Chris Tooley as its new CEO.

He replaces Milind Kangle, who left the company earlier this year.

The Advertising Standards Authority has upheld a complaint about the www.lycamobile.co.uk web site, which referred to various tariffs as offering ‘unlimited’ calls, text messages and mobile data.

Smaller print then said “Unlimited usage is subject to a fair usage of 3000 minutes/texts/MB per month per SIM. Usage in excess of your fair usage allowance will be charged at standard rates.”

In this week's edition of The Fonecast we're talking to Milind Kangle, CEO of Lycatel - the company behind new UK virtual network Lycamobile. There's also a quick preview of the forthcoming Android-powered T-Mobile G1 and our usual look at the latest mobile news headlines.

Recent figures released by ABI Research have prompted the market intelligence company to ask whether Google is losing control of the Android ecosystem.

At first glance, Android dominated smartphone shipments for the final quarter of 2013. ABI Research says 77% of the 287 million smartphones shipped in Q4 2013 were running Android.

After initially suffering from slow pick up by consumers, 4G has begun to accelerate, and is now well on the way to the forecasted one billion subscribers by 2017. In fact EE, owner of T-Mobile and Orange, recently announced the addition of 493,000 new 4G customers to its existing base of 1.2 million.

A new report has highlighted the issue of poor mobile phone coverage in rural Sussex villages. BBC Sussex invited me onto their ‘Sussex Breakfast’ radio show to explain what could be done - and, as usual, I made enough notes for a lecture rather than a three-minute interview.

Here’s what I would have liked to have said if I’d been given a disproportionate amount of time to talk.

Great news for mobile phone users. Ofcom’s new rules preventing unexpected mid-contract price rises came into force last week, which means UK consumers can no longer be surprised by their subscription charge increasing while they’re still locked into a minimum-term deal.

Mark Bridge writes:

This week, new Ofcom rules came into force. They’re designed to avoid unexpected price rises during the minimum term of a mobile phone contract. Yes, just because you signed a fixed-term contract doesn’t mean the charges can’t increase. Networks said they needed this option in case of inflation or regulatory changes. Customers felt trapped.

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.
