No credit check SIM only deals:
rolling plans from the UK's top networks

100% guaranteed SIM only

Compare 100% guaranteed SIM only plans with no credit check that will accept you even if you have bad credit history or have been declined already. SIM Sherpa is your trusty guide.

How they work

Pay up front for your SIM only plan to avoid credit checks

A bank card

There's no credit check when you pre-payCompare the deals

Mobile phone networks have credit checks in place for their pay monthly SIM only contracts, because it’s possible for people to run up large bills and then not pay.

The companies want to make sure that people have a good record of paying mobile bills. If someone has a record of not paying, it puts them off, because they think it might happen again.

The solution is to pay for your plan and usage up front. That way, there’s no risk for the mobile network. They already have the money before you make any calls, send texts and use data.

Paying up front is essentially like pay as you go. But don’t let that put you off. Loads of networks now have decent value pre-paid plans that give you a bundle of mins, texts and data, just like pay monthly.

This website (simsherpa.com) is only here to give you information about SIM only plans that have no credit check, we’re not a retailer ourselves and you don’t need to apply via us, or give us your details.

The deals we show on this page let you sign up directly to the mobile network you chose via their official websites, just like every other customer.

We’re not fans of the type of websites that lure you in promising 100% guaranteed mobile contracts and make you sign up to rip-off loans for phones.

You’re far better off dealing direct with a trustworthy mobile network than sketchy internet companies you’ve never heard of.

These rolling plans are guaranteed to accept anyone, even without a good credit history

A calendar with 30 days

Bundles of mins, texts & data lasting 30 daysSee the plans

These aren't specifically 'bad credit SIM only contracts'. They're actually just pre-paid 30-day rolling plans that let you buy a bundle of minutes, texts and data up front each month. And they're open to absolutely anyone.

There are many reasons people fail a mobile credit check like if you have no credit history, bad credit history, you're under 18 or are a student, or you've just moved to the UK.

The important thing to remember is it's nothing to worry about. There are still plenty of guaranteed SIM only deals out there with no credit check to pass.

The only difference between these deals and contract SIM only deals, is that you pre-pay for your monthly minutes, texts and data, instead of receiving a bill each month.

30-day bundles give you more flexibility than regular SIM only contracts

Hand signing a contract

More flexibility than having a contractCompare prices

Because you're not locked into a fixed contract, you're free to do what you like with your SIM.

You choose when and if you buy your monthly bundle, which means you get the advantage of all these options:

  • Stay on the same bundle if it's got the right mins, text and data
  • Buy a different bundle each month if your needs change
  • Take a break by not renewing your bundle until you're ready
  • Cancel altogether and leave with no notice period

In many ways, this is much better than 12-month bundle, where you're stuck on the same tariff and network for a long time with no flexibility.

You probably best know Lebara for offering cheap international calls worldwide but we'd actually say they're now worth considering if you want a monthly plan to use just in the UK too.

All Lebara's SIM only deals are paid for up front, which as we make clear throughout this guide means there's no credit check to pass. They offer quite a few combinations of 30-day bundles of UK minutes, texts and data.

If you have relatives, a nice bonus is that most of their deals include some form of international minutes (see the full list of countries here).

Lebara use the Vodafone network and even offer 4G data speeds in the UK now too. Overall, they're worth considering if the deal is right for you.

If you use our no credit check SIM only plan comparison tool above, you'll notice that Three come in as the lowest major network on most their plans.

Even if you've been declined by Three for a pay monthly SIM before, you can still take one of their pay as you go SIMs here, because none of them need you to pass a credit check.

You top up with credit and then either pay for usage at ultra-cheap rates (3p per min, 2p per text, 1p MB) or buy an Add-on (a monthly bundle of mins, text and data). Three are great for no credit check SIMs with big data allowances.

If you buy a monthly bundle, you'll get access to Three's famous benefit Feel-At-Home free roaming in 71 countries worldwide and their new daily Rewards app Wuntu.

We'd describe Tesco Mobile as a safe pair of hands when it comes to joining a mobile network. But if you've had a hard time getting accepted for a contract SIM only deal, there's still a way to join Tesco anyway.

Take a Tesco Mobile pay as you go SIM and there's no credit check to pass. They offer monthly bundles of minutes, texts and data called Rocket Packs that do the same job as a pay monthly SIM.

All you need to do is top up with credit up front, and then choose which bundle to swap your credit for.

You can get a decent amount of monthly data with them, although the plans work out a little pricier than Tesco's own pay monthly deals and the other specialist no credit check deal networks on this page.

Their pay as you go rates are very competitive at just 3p per minute, 2p per text and 1p per MB data, so iD Mobile are a decent option if you need a guaranteed deal.

Vodafone's pre-paid SIMs come with 'Total Rollover' benefit

Keep any minutes, texts or data you've not usedSee Vodafone SIMs

at Vodafone.co.uk
(opens in new window)

All Vodafone's pay monthly SIM only contracts need you to pass a credit check. But take one of their pay as you go SIMs here and you're guaranteed to be accepted, even if Vodafone have declined you before.

There's a choice of old-school topping up and just paying for minutes, texts and data at these rates. Or there are monthly bundles that last for 30 days and offer much better value.

One handy benefit you get on these SIMs that you don't even get on Vodafone's contract deals is Total Rollover. This lets you keep unused data and minutes you've bought as part of a bundle for next month, so they don't get wasted.

Their pricing isn't as competitive as some of the low-cost specialists like SMARTY or giffgaff. But if you're keen to join a major network with no credit check, you can with these deals.
