Apple has launched a new payment system which allows you to spread the cost of a new iPhone 7 over 20 months in instalments – without paying a penny in interest.

Mobile phone users should now be able to dodge irritating cold calls for free by texting the second opt-out number the Telephone Preference Service has launched in a week, after it emerged some were being charged to text the first number. While some users may receive a warning message stating the new number isn't free, the TPS assures us that no charge will be made.

A multi-billion pound merger between O2 and Three has been blocked due to concerns over the impact the proposed deal would have on UK mobile customers.

O2 has closed a loophole in its Priority app that meant customers were able to purchase multiple £1 meal deals on a Monday.

Most EE and O2 mobile phone customers will be hit with monthly contract price rises of 1.3% from 30 March 2016. But if you're affected you're unlikely to be able to leave your contract penalty-free, as annual inflationary price rises such as these are written into the firms' mobile contracts.

Mobile phone customers could face higher bills after Ofcom today announced it is to treble annual fees for some operators.

Top of the range mobiles are never MoneySaving, and after every big new launch it's best to wait for the top deals. But if you must get your hands on the latest iPhone 6S and 6S Plus straight away, we've rounded up the tariffs with the cheapest upfront and cheapest monthly costs so far.

O2 says it's fixed a 'network equipment' problem which left some users unable to make calls, send texts and access the internet on Monday evening. But if you've lost out financially as a result of the issue, complain and ask for a reimbursement.

EE customers without signal can now have calls routed and texts sent over wifi as the provider has this week launched a new service in a bid to combat mobile users losing signal in their own homes.

Hutchison Whampoa – owner of mobile phone network Three – has agreed a deal to buy rival mobile provider O2, subject to approval. But there's no change for customers for now.
