Best SMARTY SIM-only deals this week

Is SMARTY a good network?

SMARTY is an excellent choice if you want a highly flexible SIM only deal with prices that won’t break the bank.

All its SIM-only deals are rolling 30 day contracts, so you aren’t locked in long term, plus there are no credit checks, ideal if you’ve got a bad rating.

5G support comes as standard too, meaning you can pair one of SMARTY’s SIM only deals with the growing band of 5G smartphones.

Smarty runs on the Three network which may not be as widespread as EE but is still excellent if you live in major towns and cities, with ever-growing 5G coverage.

There are no phone contracts available from SMARTY, though, so you’ll need to have a phone primed to take your new SIM.

What SIM-only deals can I get from SMARTY?

As Three’s budget-friendly arm, what SMARTY does best is cheap and cheerful SIM-only deals.

All plans last 30 days on a rolling basis, with data allowances ranging from 4GB up to unlimited data. You’ll get unlimited calls and texts too, and 5G connectivity included where it’s available.

SMARTY also offers data-only deals to put in your tablet or mobile broadband gadget. They’re all flexible one-month plans too, with data allowances from 2GB up to unlimited.

What benefits does SMARTY offer?

• 5G on all plans
• Group Plans – save 10% on every additional SIM you get
• SMARTY app to manage your account easily
• EU roaming at no extra cost
• Wi-Fi calling

Can I use my SMARTY SIM abroad?

SMARTY lets you use your SIM when travelling in the European Union at no extra cost. While calls and texts are unlimited, there is a fair usage limit of 12GB on data.

Outside of the EU, you’ll need to log into your account and buy a special out of plan add on. Check out Smarty’s website for the details.

Cheapest SMARTY SIM-only deal this week

SMARTY's cheapest SIM deals have lower allowances, are often on longer contract terms, and may be missing some of the features and extras of a more premium SIM plan. Existing customers can sometimes snag even better deals too.

To find the cheapest SMARTY SIM option that suits you, just use our comparison table. Narrow the deals down with the filters, then use the 'sort by' toggle to order them by monthly cost. This will push the cheapest deals up to the top so you can see them first.

Can I get unlimited data with a SMARTY SIM?

Yes. SMARTY has an unlimited data SIM-only deal, at a very reasonable price. It includes unlimited calls and texts too, so your use really is without limits.

Or, you could save a few bob by opting for the more limited 200GB per month plan instead. It’s still a huge amount of data – more than most of us need – but comes at a few pounds cheaper per month.

See our guide to unlimited data deals for more info on how to find a deal.

Are SMARTY SIM-only deals cheaper than contracts?

Yes, in most cases it's cheaper to go SIM-only than to take out a handset contract - partly because it means you won't be paying any interest or extra costs on the phone itself. Buying a SIM-free phone deal and getting a SIM-only deal to put in it almost always works out cheaper in the long run.

As an extra price-saving bonus, SIM-only contracts usually last a much shorter length of time than ones with a phone… meaning you can switch to a new, even cheaper SIM as soon as you find one.

Can I keep my mobile number if I switch to a SMARTY SIM-only deal?

Yep, you can keep your phone number when you switch mobile networks, regardless of which network you're switching to or from. It's surprisingly hassle-free to sort out, too.

All you need to do is sign up to a new deal, then contact your current network and ask for a PAC - a porting authorisation code.

Give it to Smarty once you have your SIM, and the number should port across within a matter of days.

This is a far cry from having to call and beg for one back in the bad old days.

Do I need an unlocked phone to use a SMARTY SIM?

Yes, your phone needs to be unlocked - or locked to Smarty - in order to use a Smarty SIM card.

If you bought your phone outright from a retailer, it should already be unlocked and you have nothing to worry about.

However, if you're using an old phone that you got on a contract, it may be locked to your former network. In that case, you'll need to get it unlocked - but don't worry, as this is easy enough to do.

All you have to do is contact the network it's locked to, and they'll sort it out - sometimes free of charge. They may give you a code to enter, or might be able to it remotely. Your phone will be unlocked and ready for a new SIM in a few days' time.

Do SMARTY run credit checks?

No, Smarty does not run credit checks, as all of its plans are 30 day rolling deals.

This makes it an excellent choice for anyone with a bad rating who still wants to get 5G and take advantage of larger data allowances and EU roaming.

How long do SMARTY contracts last?

All SMARTY SIM-only deals last 30 days. You can keep them rolling for as long as you like – or, you’re free to change your allowance or switch to a different network whenever you want.
