Looking at what you can get on SIM only with SMARTY this May, our best-rated deal would be their 1‑month plan below, which comes with unlimited data, plus unlimited minutes and texts for £16 a month:

While this is a good enough deal to make it into the best of SMARTY's SIMs, you can beat it for price (even if you definitely want a provider that uses the Three network). See lower-priced networks' deals here:

Their £7 for 12GB plan is a decent deal for May

If you need less data, you might like the £7 SIM only deal running on SMARTY at the moment. It's a 1‑month plan, which comes with 12GB data, unlimited minutes and texts too:

It's a good enough deal to get into SMARTY's best SIMs but you can actually get a lower price for a similar plan elsewhere, even if you definitely want it to use the Three network. Here are other networks you can beat it on:

They're also offering 4GB for £5 on SIM only currently

For a smaller amount of 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 4GB data, unlimited minutes and texts for £5 a month:

SMARTY's is actually the best-priced SIM only deal in the UK at the moment for 4GB data or more. No other providers can beat it for monthly cost. Here's each network's nearest plan:

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).
