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.

Mobile phones have been hitting the mainstream news over the past few days. There was Channel 4’s report about data on second-hand phones not being properly deleted before the handsets were re-sold, there was the latest round of the Smart UK Project and there was Tim Muffett’s story about the mobile-enabled high street on BBC Breakfast this morning.

This week's podcast starts with Lenovo's purchase of the Motorola Mobility smartphone business. Was it a good deal for everyone?

We also talk about network infrastructure sharing in the UK, mobile malware, 3G coverage, misleading apps, mobile advertising, Samsung's retail plans and global tablet sales.

A new report has highlighted the issue of poor mobile phone coverage in rural Sussex villages. BBC Sussex invited me onto their ‘Sussex Breakfast’ radio show to explain what could be done - and, as usual, I made enough notes for a lecture rather than a three-minute interview.

Here’s what I would have liked to have said if I’d been given a disproportionate amount of time to talk.

This week's podcast starts with talk about money, as Google buys smart thermostat company Nest Labs while O2 UK closes its mobile Wallet product.

We're also looking at the decline of SMS text messaging in the UK, the end of the Cash4phones recycling business, an alleged security breach that wasn't what it seemed, mobile service on the Channel tunnel and the growth of 4G.
