We think the best value for money SIM only plan on SMARTY for June is their unlimited data for £15 deal. It's on a 1‑month plan and comes with unlimited minutes and texts too:

There are currently no other SIM only deals with unlimited data on other networks that can beat SMARTY's plan here. Here are other providers' closest efforts anyway:

If you don't need that much data, you might like the £8 SIM only deal running on SMARTY at the moment. It's a 1‑month plan, which comes with 50GB 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 5GB for £5 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 5GB data, unlimited minutes and texts for £5 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:

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).

They offer all their plans as 1-month no-contract deals. They have a wide range of data plans and typically share better value hidden deals with comparison websites like us which are worth keeping an eye out for.

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

You don’t get many extra benefits on SMARTY. You do get 10% off any extra plans you add to your account. On top of that, SMARTY promise not to raise the cost of your plan while you’re with them.

You’ll receive your SMARTY SIM card within 2 working days of ordering. You’ll receive a package with every size of SIM for any phone. But you can’t get an eSIM on SMARTY (these networks do offer them).

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.

You don’t need to pass a credit check to join SMARTY as you pay for your plan up front. That makes them a great alternative if you failed a credit check for a Three SIM only contract but 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).
