The best SIM deals with EE, O2, Tesco, Sky and more that can help you save £ 156 per year

Sick and tired of shelling out a fortune on your monthly phone bill? Why not switch to SIM only and save hundreds

Switching to SIM only could save you hundreds in the long run

With the cost of living rising, more and more people are thinking about how to reduce their expenses.

Getting sucked into a long phone contract could come with a pretty steep price tag, so it might be worth looking for a better deal or ditching the contract for a SIM-only deal.

According to a study by mobile operator iD mobile, it is said that one third of consumers could save an average of £ 156 per year by switching providers.

Most cell phone providers on the market offer unlimited calling and texting on sim only with a few deals even starting at as little as £ 5 per month – yes, you heard that right.

With so many deals and suppliers available, we’ve made your search easy by selecting the best deals from EE, O2, Sky and more to help you save those extra pennies.
