Why is SMARTY so cheap?

If you’re wondering why SMARTY is so cheap, it mainly comes down to how they run the network and keep things simple.

SMARTY is a SIM-only provider owned by Three, and it operates as a low-cost, online-only brand. There are no shops, no long-term contracts, and fewer extras. That cuts overheads, and those savings are passed on through lower monthly prices.

The main reasons SMARTY is cheap

1. No contracts
All plans are 1-month rolling. You’re not locked in, which also means fewer incentives and admin costs compared to traditional providers.

2. Online-only model
No retail stores or sales teams. Everything is handled online, which keeps costs down.

3. Simple plans
SMARTY avoids bundles and add-ons. You just pick a data plan, and that’s it.

4. Uses the Three network
They don’t run their own infrastructure. By using Three’s network, they avoid the cost of building and maintaining it.

5. No expensive perks
No “free” streaming or extras built into the price. What you see is what you pay for.

Can You Still Get a Referral Bonus?

Yes. Even though SMARTY is already low-cost, they still offer a refer-a-friend scheme.

If you sign up through a referral link, you’ll receive a gift card or cash reward once you’ve activated your SIM and met the qualifying conditions. The value can vary depending on the plan you choose.

Is SMARTY worth it?

If your priority is low monthly cost with no contract, SMARTY is one of the simplest options in the UK.

The referral bonus is just an extra on top. It’s not the reason to choose them, but if you’re joining anyway, you might as well take it.

Quick summary

  • SMARTY is cheap because it’s online-only with no contracts
  • Uses the Three network to reduce costs
  • Simple plans with no extras
  • Referral link gives you a gift card when you join

Referral information and free credit offer

If you find Energy Stats UK useful, there are a couple of easy ways to support the site and help cover hosting and server costs.

Thinking about switching energy suppliers?

Homeowners who join Octopus Energy using my referral link get £50 free credit after signing up.  Business users get £100 free credit, and if you’re looking at solar or a heat pump, there’s also a £100 gift card through Octopus Tech.

Finally, a £25 gift card can be claimed when having an EV charger installed through Octopus.

“Existing Octopus customer? Find out how you can benefit too. T&Cs apply (only one switching offer per household)”

Or, if you just want to say thanks, you can buy me a coffee.
