SIMO deals for February 2021
Everyone wants a good deal when buying a new SIM contract but with so much choice it can be confusing. As with any financial contract it's important to choose the right plan for you - especially if you're about to commit to a 12 month deal.
Because budget is one of the biggest factors in choosing a new deal we've compared offers across various price points. Simply decide how much you want to spend and compare deals from the top UK networks.
It is worth noting that around 50% of UK mobile consumers use up to 5GB data a month. and call and text usage is actually falling. For around £10 you can easily cover these requirements. Consider your own mobile phone use before you buy; it's not worth paying extra for allowances you won't use.
SIM deals under £10
Without the repayments for a phone included in the monthly bill, SIM only deals can be incredibly low cost – starting from as little as £5 per month. Though you won’t find many £5 deals from all the big mobile networks Three are pretty active, and there is plenty on offer from the smaller Mobile Virtual Network Operators like giffgaff and Tesco Mobile, who both use O2’s network, or Virgin Mobile on EE.
SIM deals from £10

Why show 12 month deals first?
We show 12 month deals by default because they generally present the best value for money. We do revisit this every now and again to make sure it is still true.
