The UK is beginning its week with news of a long-awaited sporting victory for Andy Murray. The telecoms world had its own much-anticipated good news last week, when European roaming rates fell again. And regardless of Neelie Kroes’ plans to abolish roaming rates completely, there’ll definitely be another roaming cut in 2014.

In our podcast this week we're discussing the new SmartWatch from Sony, talking about Firefox OS smartphones and contemplating Vodafone's partnership with Sainsbury's.

We're also looking at complaint figures, roaming charges, pay as you go pricing, joint ventures, BlackBerry's recent results and the future of Windows Phone.

A new mobile service called Mobile by Sainsbury’s is being launched this summer by Vodafone and Sainsbury’s in the UK.

It’ll run as a 50/50 joint venture with a management team of experienced mobile, retail and marketing experts from both Sainsbury's and Vodafone.

I don’t know about you but I’m delighted to see Sony Mobile getting plenty of coverage for its new smart watch and giant smartphone. The company’s impressive presence at Mobile World Congress 2013 showed plenty of promise... and I’d say it’s now delivering.

The Advertising Standards Authority has upheld complaints made about ‘pay monthly’ pricing on Vodafone UK’s web site.

Two complainants pointed out that the amount of inclusive minutes shown for a price plan was potentially misleading because every call used a minimum of one minute’s credit even if the call lasted for just a few seconds. This meant customers wouldn’t necessarily benefit from the full allowance of minutes that was being promoted.
