UK telecoms regulator Ofcom wants to ban inflation-related rises in phone and broadband contracts. Instead, it says any potential mid-contract price rises should be set out in pounds and pence.

A new forecast from research specialists Canalys shows the smartphone market is set to recover next year. Worldwide shipments declined by 12% last year but that decline is expected to slow to 5% this year.

Vodafone Group plc and CK Hutchison Group Telecom Holdings Limited have agreed to combine their UK telecommunication businesses, respectively Vodafone UK and Three UK. The merger will create a large new network operator to compete with Virgin Media O2 and EE.

UK mobile payment service Paym will close on 7th March 2023. The service, which allowed users to make and receive payments using their mobile phone numbers, was launched in 2014.

Great news for mobile phone users. Ofcom’s new rules preventing unexpected mid-contract price rises came into force last week, which means UK consumers can no longer be surprised by their subscription charge increasing while they’re still locked into a minimum-term deal.

Analyst firm Ovum has published its mobile payment and mobile advertising predictions for this year.

Ovum expects continued technology and service innovation, notably around location-based applications, in the mobile payments space in 2014.

A quick fact: nearly half of Facebook’s advertising revenue now stems from mobile ads.

That’s right – of the social network’s $1.8 billion (£1.1 billion) generated in the third quarter of 2013, 49% of it was made up of mobile advertising revenue. Last year, the channel represented only 14%.

Don't sell the steak – sell the sizzle!  That's the mantra of many salespeople. It's all about emphasising the benefits of a product rather than its features. You don't tell people about the 13 megapixel camera when they ask about the new LG smartphone, you tell them it'll capture the first steps of their precious young nephew in pin-sharp accuracy. Or something like that.

Ring-back tones offers consumers yet another way to customise their mobile phone service. Yet despite this - and the revenue opportunities that can be generated - many network operators don't provide ring-back tones.

In today's special feature we talk to Florent Stroppa of OnMobile to discover why the UK doesn't really seem to be bothered about ring-back tones... and whether the next-generation of interactive ring-back services could change this.
