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.

The Smart UK project is an annual government-supported competition looking for the UK's Most Innovative Mobile Company.

A few days ago, all 20 companies on the competition shortlist gave a short presentation to the Smart UK panel of judges. Afterwards, Mark Bridge spoke to some of the entrants to discover exactly what they had to offer - and how they planned to disrupt the mobile industry.

In this week's podcast, James Rosewell and Mark Bridge talk about the new Zapp mobile payment scheme, Google's healthcare plans and an ultra-secure smartphone.

Also on the agenda are HP's new phablets, Jimmy Wales joining a UK MVNO, Apple's in-app purchases and plenty of research about tablets.

In this week's show we look at Google's new product announcements, O2's closure of its mobile telecare service and the clearance of radio frequencies for 4G services.
