SMARTY's best SIM only deals
The SIM only deal on SMARTY we rate highest this month
We think SMARTY's best value option on SIM only this September is their £16 a month plan below, which comes with unlimited data, plus unlimited minutes and texts on a 1‑month deal:
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's where you can beat it on other networks:
SMARTY's 5GB for £6 plan is a good option too
If you wouldn't get through that much data, we think this 5GB is one of the best SIM only plans on SMARTY too. It's on a 1‑month deal, comes with unlimited minutes and texts - all for £6 a month:
In comparison to the rest of SMARTY's current SIM only plans, it's one of the best. But it is beatable on price, even if you're set on joining a provider that uses the Three network. See lower-priced networks' deals here:
Their £12 for 100GB plan is a decent deal for September
To get a bigger data allowance, we also think this £12 SMARTY SIM is one of their best options. It comes with 100GB data, unlimited minutes and texts on a 1‑month deal:
It does enough to get into our pick of SMARTY's best SIMs but that doesn't mean it's unbeatable on price. Other providers (even ones that use the Three network) can beat it. Here are other networks you can beat it on:
They're also offering 8GB for £7 on SIM only currently
If you don't need that much data, SMARTY's £7 SIM below is another of their best deals this month. For £7 a month, it offers 8GB data, unlimited minutes and texts on a 1‑month plan:
Compared to SMARTY's other deals, this comes out among the best. But it's worth knowing you can get a lower price elsewhere, even on other providers that use the Three network. See the networks with cheaper plans here:

How SMARTY compare for benefits and SIM only prices
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.

What else you should know about SMARTY’s SIM only deals
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).
