SIM Only deals can be a lot cheaper than getting a new phone on contract, and these deals are proof of that – at £5 or less these are the very cheapest SIM Only deals you can get. Yet in some cases you still get a lot with them, including 5G and generous allowances.

Which networks offer SIM Only deals for £5 or less?

Currently, the networks that offer SIM Only deals for £5 or less are 1pmobile, Asda Mobile, Lebara, Lycamobile, Talkmobile and Three. 

All the other networks SIM only deals start at a higher price than £5 a month, including GiffGaff, iD Mobile, O2, Sky Mobile, Smarty, Tesco Mobile, Vodafone and Voxi.

Which is the best value deal for under £5?

Lycamobile currently have a great value deal for just £1.99 for the first 6 months, which is a on 1-month rolling contract. It comes with 5GB data, 1000 minutes and 1000 texts and resort to £5 a month after the first 6 months.

If you are looking to go with one of the big 4 networks in the UK the only available deals is the 3GB data deal which costs £5 a month

If you are willing to spend a little more in the long term we'd also recommend Talkmobile's 60GB data deal, which is half price for the first 3 months at £4.95. However, that'll rise to £9.95 for the other 9 months of the 12-month contract.

Why choose a SIM Only plan?

SIM Only plans have a lot of advantages to them. For one thing, they’re typically the cheapest type of plan – and these deals in particular are extremely affordable.

For another, they’re often short-term, so you’re only tied in for 30 days in many cases, rather than having to commit for two years as you do with most handset plans.

Which SIM card size do I need?

Most people will need a nano SIM, as these are used by the vast majority of remotely recent phones. However, your network will send you all three possible sizes, so you can simply select the one that fits your phone.

Can I get 5G on a SIM plan for £5 or under?

Yes, currently you can get 5G SIM only deals for £5 or less on 1pmobile, Lycamobile, Lebara, Talkmobile and Three.

Just look out for the box saying ‘5G’ on the deals above if that’s important to you.

Can I get a SIM Only plan with no credit check?

Yes, some networks offer SIM only plans with no credit check, especially on cheap plans like these. To be sure you won’t be credit checked, select the ‘no contract’ filter on the contract length dropdown above.
