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.

Compare mobile networks on SIM-only deals

Take a look at the different SIM-only packages and extras offered by mobile networks:

  • O2 - Customers get exclusive offers and vouchers for high street stores, restaurants and events through O2 Priority.
  • Vodafone - Enjoy entertainment subscriptions to Spotify, Prime Video and Sky Sports through Vodafone's Red Entertainment packages.
  • Giffgaff - Great value-for-money 30-day rolling SIM deals
  • Three - Reasonably-priced SIM deals with excellent roaming perks
  • iD Mobile - Affordable and simple plans with data rollover on the Three network

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.

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.

What do SMARTY plans include?

Smarty plans come with a ton of great features. These include:

  • 30 day rolling deals. There are no long term contracts here, meaning you can cancel and change anytime you like.
  • Inclusive EU roaming up to 12GB, a big deal considering some major networks now charge when using your phone overseas.
  • Unlimited calls and texts on all deals (unless you have a data only plan)
  • No speed caps whatsoever
  • As much tethering as you like in the UK
  • No need for a credit check
  • All SIM sizes catered for, including normal, micro and nano
Frequently asked questions

What SIM-only deals can I get from SMARTY?

Smarty has some truly excellent value plans, whether you want a bit of data for basic use or need an endless supply for all your streaming, gaming and web browsing needs. There are currently 4GB, 8GB, 12GB, 30GB, 100GB and unlimited data deals available.

Smarty also has a range of ‘data back’ deals which offer 1GB, 2GB and 3GB per month and cash back for whatever data you don’t use. These are great for light users on a tight budget.

Smarty’s flexible one-month contracts mean you can change your plan each month too.

How do I choose a SMARTY SIM-only deal?

Finding the right Smarty SIM deal for you couldn't be easier. Have a look at the deals in our comparison table, and pick the one you like best.

You can adjust the filters at the side to only show the SIMs that fit what you need, and can even compare Smarty plans with those from other networks too. When you spot one you like, simply select it, and we'll take you straight to Smarty's website so you can order it.

When you're comparing, think about what's most important from your deal:

  • Data allowance - How much do you use 4G mobile internet? If you only use your phone to scroll through Facebook, browse the web a bit, and use WhatsApp, you'll be fine with a small allowance. On the other hand, hungrier users who stream on the go, use their phone for work, or download large files may want 10GB or so per month. Most of us, however, will find a data allowance between 2-5GB suits us perfectly.
  • Calls and texts allowance - Think about how much you make calls on your mobile, and how many SMS texts (not WhatsApp or Facebook messages) you send in a month. Low to mid-data allowances are available from Smarty at reasonable prices, though heavier data users should probably consider other networks.
  • Contract length - With SIM plans, you usually have a choice between 30-day or 12-month contracts. Longer contracts generally have lower monthly costs, while a 30-day one can be changed at any time. It's worth going for a 12-month deal if you're happy to commit for a full year - though if you want a bit of flexibility, so you can change your monthly allowance or switch networks entirely whenever you like, go for a one-month SIM instead.
  • Price - On a budget? Set a maximum monthly price using the filter at the side, or sort all the deals by cost to see the lowest-priced ones first. See the section below if you need a bit of help finding the cheapest possible deal.
  • SIM card type - Make sure you get the right size SIM card for your phone. Most networks these days offer 'combi-SIMs' that can fit any device, so go for one of those if you're not sure.

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.

What size SIM card do I need?

There are five kinds of SIM card, sized to fit different devices:

  • Standard SIM - A classic full-size SIM, and the biggest of all. Generally only used in older phones, including old feature phones.
  • Micro SIM - A mid-size SIM, smaller than a standard one.
  • Nano SIM - The smallest SIM of all, and usually the SIM of choice for modern smartphones. This is the one you need for an iPhone 13 or newer, Samsung Galaxy S21 5G or newer, or a Google Pixel 6.
  • Combi-SIM - A clever three-in-one SIM. You can change the size of this SIM to make it fit in any phone. The majority of networks offer these as standard.
  • eSIM - These are built into the phone and are not hugely common, although more manufacturers are looking to offer them going forward.

To find out what size SIM you need to get, take a look at your device's manual, or check the manufacturer's website.

If you're still not sure, don't worry - most networks send out combi-SIMs to make life easier.

What does SMARTY offer in the way of tablets and dongles?

Smarty offers a full range of data only SIM plans designed expressly to work with tablets and dongles. All you need to do is pick the right offer for you.

They’re great for iPads or as a handy back up in case your home broadband goes down.

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.
