SMARTY's best SIM only deals

The best SIM only deal on SMARTY this month

Out of all the SIM only plans available this April 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:

It might not be the lowest-cost SIM only deal with unlimited data on the entire market but if you're sure you need a SIM using the Three network, it is the best-priced. Here are other networks you can beat it on:

Or their £10 for 60GB SIM plan is worth a look too

If you need less data, you might like the £10 SIM only deal running on SMARTY at the moment. It's a 1‑month plan, which comes with 60GB data, unlimited minutes and texts too:

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. See the networks with cheaper plans here:

SMARTY are also offering 50GB for £8 on SIM only

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 50GB data, unlimited minutes and texts for £8 a month:

It isn't actually the cheapest 50GB 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. Here's which other networks can beat it:

They've also got a 5GB for £5 SIM plan at the moment

If you don't want so much data, 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:

You have got other cheaper options if you don't need your SIM to be on a provider that uses the Three network. But if you do, it is the cheapest current deal available. See where you can get it for less 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).
