Ofcom has published research on mobile phone call quality from the ‘big four’ UK network operators.

It’s used data from mobile analytics specialist RootMetrics to better understand consumers’ experience of making phone calls on the EE, O2, Three and Vodafone networks.

Ofcom has scaled back its plans to increase the licence fees paid by UK mobile networks for the 900MHz and 1800MHz spectrum bands initially used for 2G and 3G services.

It previously proposed increasing overall charges paid by the ‘big four’ mobile network operators from £39.7 million for the 1800MHz spectrum up to £170.4 million.

UK communications regulator Ofcom has published an online guide to help customers unlock their mobile phones.

Mobile network operators may electronically ‘lock’ mobile phones to their network when customers buy the phone. It’s necessary to unlock these phones before they can be used with a different network provider... and this is sometimes chargeable.

New research published by UK communications regulator Ofcom shows that signing up to the Telephone Preference Service reduces the number of unsolicited ‘live’ marketing or sales calls by around a third.

Organisations are legally required to ensure they don’t call numbers registered on the TPS unless they have the consumer’s consent to contact them.

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.
