Martin Lewis issues warning to mobile phone customers with bills of more than £9 per month

Martin Lewis has put out an urgent warning for people paying over £9 a month on their phone contract.

Yep, just when you thought it was enough that your weekly shop, and electricity and gas bills had gone through the roof, there's more good news.

The Money Saving Expert says people who pay monthly for their device need to act quick to avoid losing hundreds of pounds.

And those of you who are out of contract, he says it's time to start looking for a new deal.

That's because each year in April, broadband and phone companies raise their prices in line with the Consumer Price Index (CPI) plus an additional 3-3.9 percent.

And this month saw a hike of 17 percent, which is enough to make a fairly hefty dent in your wallet, especially if you're already paying over the odds for your contract.

So while the increase has already set in, Martin says there's still time to get out and save yourself some money.

In a post to his site, the MSE pointed to a raft of sim-only deals, which he says are an absolute bargain.

For example, he highlighted a deal with Three, which offers a 100GB sim for just £8.75 per month, while you can get a 20GB sim from TalkMobile for just £7.95 a month for 12 months.

However, he warns that this and other offers run out on Sunday (30 April), so you best be quick about it.

Now, if you're paying more than this a month but only using the same amount of data, it's a no brainer, right?

According to one poll, Martin found that 88 per cent of respondents said they doing just that, paying over £8 a month, with 60 percent forking out more than £15 a month, and 34 percent paying over £30.

He said: “So big savings can be had, provided you’re one of the 14 million households that are out of contract."

To help with the search, Martin's team also created a Cheap Sim comparison tool, which allows you to filter through different networks to find the best deal for you.

And once you've got that sorted, it might also be time to have a look at your air fryer.

Over the past few months, it seems like every Tom, Dick, and Harry has got one of these things, relentlessly posting about it on social media.

But are they all they're cracked up to be? Well, yes and no.

An oven costs 21p to use on average and a 800W air fryer costs 13.6p to use.

"But if you own an air fryer that is a lot more powerful, you could be using near enough the same energy as an oven," Martin explained. "For example the 2,000W air fryer costs 34p per use, that’s 13p more than an oven.

"And the biggest factor is the quantity of food you’re cooking. [...] Cooking the same thing twice in an 800W air fryer could cost you more than 26p, which is more expensive than cooking in the oven.

"If you're cooking something small and simple in there, it's probably cheaper in the microwave and similarly the air fryer."
