Google’s big announcement last week involved the company introducing Android v4.3 (as expected), launching a new Nexus 7 tablet (as expected) and also revealing a ‘Chromecast’ HDMI adaptor that’ll stream from most portable devices. That was more of a surprise.

The Mobile by Sainsbury’s service, which was set up earlier this month as a joint venture with Vodafone UK, has announced its pricing.

As well as offering a basic ‘pay as you go’ mobile phone service with standard calls at 8p per minute and text messages costing 4p each, there are also three 30-day allowances.

In our podcast this week we're discussing the new SmartWatch from Sony, talking about Firefox OS smartphones and contemplating Vodafone's partnership with Sainsbury's.

We're also looking at complaint figures, roaming charges, pay as you go pricing, joint ventures, BlackBerry's recent results and the future of Windows Phone.

A new mobile service called Mobile by Sainsbury’s is being launched this summer by Vodafone and Sainsbury’s in the UK.

It’ll run as a 50/50 joint venture with a management team of experienced mobile, retail and marketing experts from both Sainsbury's and Vodafone.

Oh, how cheerful we were last Monday. Apple previewed iOS6, which will bring mobile tickets (and 200 other new features) to the iPhone and iPad this autumn. Vodafone cut the cost of using your phone in Europe with its flat-rate £3-per-day EuroTraveller deal and a few days later Three came up with its own ‘unlimited’ European data roaming.

Yet by the end of the week there were fewer smiles in the mobile industry.

I noticed a new phenomenon at Mobile World Congress this year: Beer O’Clock. Come 5pm Monday through Wednesday, companies with larger booths would break out the Cerveza, Vino, Cava and a small number of Orange juices. All very sociable and fun… until the music started.

So, that’s another Mobile World Congress in the bag. Yes, it was bigger than ever. Just like last year. Just like the year before, too.

I was ready to poke fun at IBM for its sponsored graffiti wall at Mobile World Congress this year. Graffiti and IBM don't have a comfortable history, as anyone who remembers the Linux campaign from 2001 will tell you.

Some companies have saved their big announcements for the week of Mobile World Congress. Samsung and Nokia, for example. Others have issued a press release in advance.

Vodafone’s admission last week that ‘some customers’ may have been experiencing issues with mobile services came three weeks late for me. I’ve been having my own ongoing battle with the network since the beginning of the month.

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.
