A promotional deal with EE has seen 40 black cabs in London and 10 in Birmingham turned into mobile WiFi hotspots. Each taxi has been given its own 4G data connection via a MiFi wireless router.

The promotional 4GEE campaign will run for three months.

London-based Eyetease Limited says it’s received approval from Transport for London to introduce a new WiFi service in London black cabs.

The service, which is called CabWiFi, will be free to passengers for 15 minutes after they’ve watched a 15-second advertisement. Drivers will be able to use the service via their own password.

greentomatocars, which was established in 2006 as London’s first green minicab company, is now offering free WiFi in all its vehicles. It’s thought to be the first passenger car company in Europe to install a mobile hotspot service.

The company operates 300 Toyota Prius hybrid cars as well as people carriers and executive vehicles in the capital.

A new mobile app called Click A Taxi has launched in the UK and Ireland, promising coverage across all towns and cities. It’s already available in Denmark, Sweden and Norway.

The Click A Taxi app is available for iPhone and Android devices. Customers who book via the app are located by GPS; the nearest participating taxi company is then located and the app provides regular updates on the arrival time. There’s no charge for the app and no fee for booking a journey.

Get Taxi promises ‘a simpler, faster way to order taxis from your mobile phone’. But there’s much more to this ambitious company than its free mobile app. I spoke to Neal Fullman, the company’s CEO, to find out more.

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.
