Are each of SMARTY's SIM only deals the cheapest in the UK for the data they give you? We compare with other networks to find out. SIM Sherpa is your trusty guide. Last updated: 1st December 2022.

SMARTY's best SIM only plan this December in our opinion is their £16, 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 £12 SIM with 120GB 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 120GB data, unlimited minutes and texts for £12 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 £8 for 30GB plan

For less data to use each month, have a look at SMARTY's 30GB SIM below at £8 a month, as it's another good deal. It's on a 1‑month plan and comes with 30GB data, unlimited minutes and texts:

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:

Their 16GB for £7 SIM is another good option

If you wouldn't get through that much data, another option for you on SMARTY, is their 1‑month SIM below, which costs £7 a month for 16GB 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 6GB for £6 plan is a good option too

For a smaller chunk of monthly 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:

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:

Their £5 for 4GB plan is a decent deal for December

If you don't need that much data, we think this 4GB 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 £5 a month:

It can actually be beaten on price if you don't need your SIM to be with a provider that uses the Three. If you do need that, it is the cheapest SIM with 4GB data or more. Here are the networks offering it cheaper:

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).

All of their plans are 1-month deals. They offer a wide range of data plans, and they usually share hidden deals with comparison websites like us that are even better than their usual range.

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

There aren’t a lot of benefits on SMARTY. They do offer a straight 10% discount on additional plans added to your account. And there are special plans that give you money back for unused data, but these aren’t quite as great value.

Your SMARTY SIM card will ship within 2 working days and the package you receive will contain every size of SIM to fit any phone. SMARTY don’t yet offer eSIMs (see which networks do here).

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.

As you’re paying for everything up front, there are no credit checks to pass to get on a SMARTY SIM. They’re a great choice if you’ve been rejected for a SIM only plan on Three but still 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).
