Compare SIM only deals
Keep your phone and compare the part you are actually paying for: data, monthly price, network and how long you are tied in, on every deal below.
Deals come from our comparison partner and MoneyHQ may earn a commission if you take one.
SIM only deals by network
Already know which network you want? Each page is the same comparison, fixed to that network.
SIM only deals by what you need
Know what matters most? Each page is the same comparison, narrowed to it.
Deals first, not pictures of SIMs.
A SIM decision turns on four things you can read in seconds: data, price, network and how long you are tied in. The comparison shows all four on every deal and lets you filter on each.
The question that matters most. Filter to the allowance you actually use, or leave it open and read the lot.
Narrow by network, and by whether you want a rolling plan you can leave any month or a longer contract.
Provider, data, price, contract, the network it runs on, and the cost over the term where it can be stated.
The brand on the SIM is not always the network.
Many SIM brands rent one of the UK’s four mast networks. Two brands on the same host network give you the same signal at different prices. Where a brand states its host network, the card will say so; where it does not, the card stays quiet rather than guessing.
A £10 SIM that rises in April is not a £10 SIM.
Where a plan’s term and rises are stated, the board will put the cost over the contract beside the monthly price. A rolling plan gets no invented total: you can leave it next month, and a “first-year cost” would be an assumption about you, not a fact about the plan.
