UK virtual mobile network Ovivo Mobile has closed, affecting what’s thought to be tens of thousands of customers.

The network has posted a message on its website that says “We are very sad to announce that for reasons beyond our control, OVIVO Mobile is closing down on the evening of Wednesday 19th March 2014.”

The UK has a new advertising-funded mobile phone network. It’s a virtual mobile network called Ovivo Mobile that’ll use the Vodafone network and has been developed through mobile virtual network aggregator Cognatel.

The SIM-only prepaid service will offer free monthly usage in exchange for targeted mobile advertising.

Mobile Virtual Network Aggregator Cognatel, which works with Vodafone in the UK, has created a new virtual mobile network for what’s described as the UK’s first customisable mini mobile phone.

CyCell will run the MVNO with a ‘white label’ credit card sized mobile handset that can be designed within days. Pre-programmed numbers can be linked to printed buttons on the phone, with all the call routing based within the network.

Fixed-line telecoms provider Alpha Telecom has announced the launch of a UK virtual mobile network called Alpha Mobile. It's a prepaid mobile service that's expected to be available from over 90,000 retail stores across the UK by the end the year.

Buying a £30 SIM from the MVNO will give customers what the company describes as 'unlimited calls' to landlines and/or mobiles in more than 75 countries.

Vodafone UK has announced a new partnership with a mobile virtual network aggregator. It's now working with Cognatel, a relatively young London-based MVNA.

Mobile phone faults pose a daily problem for mobile phone retailers. According to mobile diagnostics expert Cellebrite, 60 per cent of cases are software-related issues with the smartphone, and can be resolved within minutes.

Last week a major retailer with a significant online presence announced plans to release its own-brand smartphone by the end of the year. No, not Amazon. This news came from Tesco.

While the Galaxy S5 is an evolutionary product, there is not enough in there to make people upgrade from the 4. It doesn't push the envelope in any real way; we are in a sort of stasis now when it comes to smartphone innovation.

The Smart City is on its way. All over the world more and more cities are connecting all areas of their infrastructure. Pisa in Tuscany, for example, aims to improve its traffic management with a machine-to-machine (M2M) solution and a Big Data service provided by Deutsche Telekom.

“Hey, everybody, we’re releasing a new flagship smartphone that carries all the hopes of the company with it. If this sells well, we could be saved. If not, it could be disaster.”

“Great. What shall we call our new phone?”

“Oh, we’ll give it the same name as the previous model. That’ll be fine.”

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.
