Martin Lewis says sending two texts could save hundreds of pounds with more prices set to rise

Martin Lewis is encouraging mobile phone users to send two text messages which could possibly save you hundreds of pounds a year.

He told viewers: "Last week I told you broadband and mobile bills are going up 14 percent in April for most of the big firms. What I want you to do first is I want you to check if you're out of contract.

"Over nine million of you are and are overpaying.

"What you need to do in most cases is text INFO to 85075 on your current phone. And that should tell you whether you have termination fees to leave your contract."

Lewis added: “If you're out of contract there are actually some of you - outrageously and this should not be allowed - who have got a contract with a handset and once you paid the handset off, they keep the price at the same level so you're still paying the with-handset price even if you're no longer using it."

Lewis said the second number you should text allows you to take your mobile phone number with you to a different network if you choose.

“If you want to keep your number, text PAC to 65075 on your old phone, they will send you your PAC code and you use this with your new provider as a way to keep your old number. Of course you could use this as a way to haggle with your existing provider," he explained.

The increased prices are to align with the Customer Price Index (CPI) inflation of 10 percent, which was announced last week.

Martin previously warned that many broadband and phone providers use inflation in addition to roughly four percent, which reflects their annual price increases.
