UK communications regulator Ofcom is working with fixed-line and mobile network operators to inform consumers about forthcoming changes to telephone call charges.

Calls from UK mobile phones to 0800 and 0808 ‘free phone’ telephone numbers will be free to all customers from next summer. In addition, call rates to other numbers that begin with 08, 09 and 118 will be clarified for fixed-line and mobile customers.

BT has won a Supreme Court ruling that could see it reclaiming millions of pounds from UK mobile network operators.

The case dates back to 2009, when BT announced new termination rates for telephone numbers that began with 08. These rates varied depending on the amount that the originating network charged the caller.

The UK’s Advertising Standards Authority has ruled that a TV advertisement for Three didn’t explain the network’s free calls policy clearly enough.

A total of eleven people challenged the claim “we’ve made 0800 numbers free” because this only applied to new customers or new 24-month contracts.

In this week's podcast we talk about two of the big announcements from Google I/O: a new version of Android and the retail launch of smartwatches powered by 'Android Wear'.

We also talk about Android-based smartphones from Nokia and Blackphone, network complaints in the UK, a reduction in European roaming charges and mobile ticketing.

UK telecoms regulator Ofcom has published proposals that would see the wholesale cost of connecting mobile phone calls dropping to less than 0.5p per minute within three years.

Termination rates have fallen by 20p per minute within the past 20 years and are currently about 0.8p per minute.
