Vodafone and UK-based pharmaceutical company AstraZeneca have announced a global partnership that’ll see them using mobile health services to help patients with cardiovascular conditions.

The collaboration will work in partnership with healthcare professionals, who’ll enable patients to use mobile and internet-based mHealth services during their treatment.

The UK’s major mobile network operators and the UK Information Commissioner’s Office (ICO) are now all using the GSMA’s Spam Reporting Service to deal with unwanted SMS text messages.

Although networks have offered spam reporting services for several years, the involvement of the ICO will increase the likelihood of offenders being identified and fined rather than simply being blocked.

Producing mobile phones for older customers requires much more than big buttons and a simple interface. At Mobile World Congress last month we spoke to two major players in this growing sector: Swedish company Doro and Austria's Emporia Telecom.

Our first conversation was with Harald Obereder, Chief Technology Officer at Emporia, who spoke to Mark Bridge about handset design and user interface design. This was followed by an interview with Chris Millington, Managing Director for Doro UK and Ireland, about research and development in the 'senior tech' market.

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.”

We begin this week's programme by looking at Vodafone's acquisition plans in Spain before moving on to discuss universal mobile chargers and 4G roaming.

There's also time to talk about UK mobile coverage, EE's new customer tracking service, contactless transactions and a smartphone camera that can identify objects hidden behind something else.
