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: 3rd August 2022.

From all the options SMARTY have got available this August on SIM only, we think this £16 1‑month deal is their best. For your £16 a month, you get unlimited data alongside unlimited minutes and texts:

While it's good enough to be in our pick of SMARTY's best SIM only deals, other providers do still have similar plans for less, even ones that also use the Three network. See lower-priced networks' deals here:

We also like their £10 for 50GB plan

For a smaller chunk of monthly data, we also think this £10 SMARTY SIM is one of their best options. It comes with 50GB data, unlimited minutes and texts on a 1‑month deal:

This is actually the leading price in the UK at the moment for a SIM only deal with 50GB data or more. The plans under the dropdown are the next nearest you can get to SMARTY with other providers:

Their 4GB for £5 SIM is another good option

If you don't need that much data, SMARTY's £5 SIM below is another of their best deals this month. For £5 a month, it offers 4GB data, unlimited minutes and texts on a 1‑month plan:

You can beat it for price if you don't need your SIM to be with a provider using the Three network. But if that's a must, then it is the lowest-cost SIM with 4GB data or more. See the networks with cheaper plans here:

SMARTY's 12GB for £7 plan is a good option too

If you need more data, the next best SIM only plan on SMARTY in our opinion is their 1‑month one below. For £7 a month, you get 12GB data, plus 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'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).

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).
