Out of all the SIM only plans available this July on SMARTY, we'd say their best value deal is their 1‑month SIM below, which gets you unlimited data, plus unlimited minutes and texts for £16 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:

£12 for 120GB is SMARTY's next best SIM deal in July

If you need less data, have a look at SMARTY's 120GB SIM below at £12 a month, as it's another good deal. It's on a 1‑month plan and comes with 120GB data, unlimited minutes and texts:

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). Here are other networks you can beat it on:

There's also a nice 40GB for £10 plan with them this month

For a smaller amount of data, another option for you on SMARTY, is their 1‑month SIM below, which costs £10 a month for 40GB data and comes with unlimited minutes and texts:

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. See the networks with cheaper plans here:

Or their £6 for 6GB SIM plan is worth a look too

If you don't want so much data, SMARTY have got a £6 deal on SIM only we think's worth looking at. It gets you 6GB data, unlimited minutes and texts and it's a 1‑month plan:

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. Here's which other networks can beat it:

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).
