SMARTY's best SIM only deals

We think the best value for money SIM only plan on SMARTY for June is their unlimited data for £16 deal. It's on a 1‑month plan and comes with unlimited minutes and texts too:

While it's good enough to be in our pick of SMARTY's best SIM only deals, other providers do still have similar plans for less, even ones that also use the Three network. See who's offering it for less here:

Their £12 for 100GB plan is a decent deal for June

If you don't need that much data, you might like the £12 SIM only deal running on SMARTY at the moment. It's a 1‑month plan, which comes with 100GB data, unlimited minutes and texts too:

It's definitely one of SMARTY's best. But it's not market-leading. You can get a similar plan on other providers for less, even if you need your SIM to use the Three network. Here's where you can beat it on other networks:

They're also offering 12GB for £7 on SIM only currently

For less monthly data, we'd say this is one of SMARTY's best deals on SIM only this month too. It's a 1‑month plan, comes with 12GB data, unlimited minutes and texts for £7 a month:

Even though it's in our pick of SMARTY's best SIM only deals, you can actually beat it on price with other providers, including ones that also use the Three network. See lower-priced networks' deals here:

£5 for 4GB is SMARTY's next best SIM deal in June

If you need less data, have a look at SMARTY's 4GB SIM below at £5 a month, as it's another good deal. It's on a 1‑month plan and comes with 4GB data, unlimited minutes and texts:

It's currently the best priced 4GB data or more SIM only deal on a provider using the Three network, even if you can beat it on price if you're open to ones not on Three. Here are other networks you can beat it on:

Our full review of SMARTY has moreRead our full review

(opens in new window)

In our full review of SMARTY we like the fact that you get full access to Three’s brilliant 5G network while also getting good WiFi calling and 4G calling (see our Three vs SMARTY guide here).

All of their plans are 1-month deals. They offer a wide range of data plans, and they usually share hidden deals with comparison websites like us that are even better than their usual range.

SMARTY are usually one of the cheapest of all UK networks, and are probably the cheapest provider on Three’s network (alongside iD Mobile).

There aren’t a lot of benefits on SMARTY. They do offer a straight 10% discount on additional plans added to your account. And there are special plans that give you money back for unused data, but these aren’t quite as great value.

Your SMARTY SIM card will ship within 2 working days and the package you receive will contain every size of SIM to fit any phone. SMARTY don’t yet offer eSIMs (see which networks do here).

After your SIM arrives you’ll have 14 days to return it if you’re not satisfied. You’ll only get a refund for what you haven’t used. Here are the full details on how to return your SMARTY SIM.

As you’re paying for everything up front, there are no credit checks to pass to get on a SMARTY SIM. They’re a great choice if you’ve been rejected for a SIM only plan on Three but still want to use their network.

If you want to switch over to SMARTY from another network and you want to keep your number you’ll have to request a PAC from your current provider and send it to SMARTY when you’re ready to switch (here’s how).
