A SIM only deal is a mobile phone contract where you pay a standard monthly fee for your data, calls and texts, but don’t also pay for a phone each month on top.
And with the single biggest factor affecting the cost of phone contracts being paying off the handset itself, it’s no surprise that SIM free plans are considerably cheaper.
So if you’ve already got a decent phone that you’re happy with, we’ve rounded up the very best SIM only deals out there this July 2017 below, to help you save even more, including unlimited internet from Three as well as a free £50 gift card when you buy from Carphone Warehouse.
Switching to a SIM only deal could save Brits a total of £3.4 billion per year, with the average Brit spending £92.06 more a year than they need to on an overpriced phone contract, according to research from HandsetExpert.com.
