SMARTY's best SIM only deals
This month's overall best SMARTY SIM only deal
SMARTY's best SIM only plan this December in our opinion is their £15, 1‑month deal below, which comes with unlimited data, plus unlimited minutes and texts for your money:
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 £8 SIM with 32GB is our next favourite this December
If that's more data than you need, 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 32GB data, unlimited minutes and texts for £8 a month:
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:
We also like their £5 for 5GB plan
For less data to use each month, have a look at SMARTY's 5GB SIM below at £5 a month, as it's another good deal. It's on a 1‑month plan and comes with 5GB data, unlimited minutes and texts:
It isn't actually the cheapest 5GB data or more SIM available overall this month but if you definitely need your plan to use the Three network, it is the lowest cost option. See the networks with cheaper plans here:
Their 125GB for £12 SIM is another good option
For those needing even more data, another option for you on SMARTY, is their 1‑month SIM below, which costs £12 a month for 125GB data and comes with unlimited minutes and texts:
It might be one of SMARTY's best deals on SIM only but you can get a lower price for a similar plan on other providers, even ones that use the Three network. Here's which other networks can beat it:
SMARTY's 8GB for £7 plan is a good option too
For a smaller chunk of monthly data, SMARTY have got a £7 deal on SIM only we think's worth looking at. It gets you 8GB data, unlimited minutes and texts and it's a 1‑month plan:
This is good for SMARTY but it's not an unbeatable price. You can get similar SIM only plans for less with some other providers, even ones that also use the Three network. See where you can get it for less 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).
