SMARTY Mobile review: is SMARTY any good?

smarty logo

Powered by Three, SMARTY offers a reliable 4G and 5G coverage and simple SIM-only plans – all at low costs. We weigh up everything that’s good and bad about SMARTY in our one-stop review.

Our SMARTY review in summary

SMARTY stands out with its affordable range of SIM-only plans, providing data at a lower price point than many other networks.

It may be a smaller company, but it’s part of parent company Three – meaning that you’ll benefit from Three’s widespread 3G and 4G coverage. All SIMs now come with superfast 5G at no extra cost, so you can access Three's expanding 5G network.

However, SMARTY lacks phone plans or long-term contracts – you’ll need to look elsewhere for that.

SMARTY SIM-only plans

While SMARTY solely offers SIM-only deals, it really shines in this area.

It has six plans, starting at 4GB for £6 a month to unlimited data for £20. All of which include unlimited calls and texts as standard, as well as unrestricted tethering in the UK and free EU roaming.

They’re all one-month rolling plans too, so you can cancel anytime you want. You also have the option to pause your account for up to six months.

One unique selling point of SMARTY is its data discount plans. If you choose these, you’ll get money back for any unused data at the end of the month.

SMARTY phone contract plans

SMARTY doesn’t offer phone contracts, just SIM-only plans.

But if you’re wanting to keep your device, or buy a new one outright, this may suit you more.

SMARTY coverage

SMARTY is powered by Three, so it offers a strong 4G network that covers 99.8% of the UK.

All SIMs are 5G ready too, so you can enjoy those top speeds. But it's best to first check if Three's 5G network covers your area, and which is the best 5G network for you.

SMARTY roaming

While some major networks are dialling back on inclusive mobile roaming, SMARTY still offers free EU roaming across all its plans.

So if you’re travelling in the EU, your SIM-only plan works as normal, at no extra cost. For mobile data, you’ll have a fair use limit of 12GB a month, but that should be more than enough to cover your holiday needs.

If you’re travelling outside the EU, you’ll need to buy an ‘out of plan’ add-on. The cost depends on the country you’re travelling to, so check before you go.

SMARTY customer service

SMARTY doesn’t currently provide a phone number you can call. But you can get in touch using the web chat – either with its SMARTY bot, available 24/7, or with the support team.

Or you can send an email, although it’s a bit slower than contacting the web chat team.

It’s worth noting that SMARTY has one of the highest TrustPilot ratings of any network. At the time of writing, it’s leagues ahead of a number of household-name networks when it comes to customer satisfaction.

SMARTY stores and offline experience

SMARTY is 100% online. You can use its online dashboard to manage your account, as well as read the support articles and FAQs for tips.

If you need more help, you can get in touch by web chat or email.

SMARTY's deals and incentives

There’s a Group plan, where you can save 10% on up to eight SIMs – useful if you have multiple devices, or if you want to bring your family accounts together in one place.

Its ‘refer-a-friend’ system is also rather generous. For every friend that joins SMARTY thanks to you, both of you get a free month. So if you manage to refer twelve friends, you could get a whole year free.

Finally, if you sign up during promotional events, like Black Friday, you might be able to bag a discount on certain plans.

SMARTY pricing

SMARTY’s SIM-only plans are among some of the most competitive on the market. It offers more data at lower costs than the likes of giffgaff and VOXI, which are already some of the cheapest networks out there.

You’d be hard-pressed to find a more low-cost monthly plan without having to be tied to a contract.

Still, if you’re willing to commit to a 12-month or 24-month contract, you might be able to find even cheaper elsewhere – with major networks like Three, BT Mobile and EE offering great value plans in the longer term.

Pros and cons of choosing SMARTY mobile

Pros

  • Low cost
  • Flexible and free to cancel anytime
  • Unlimited tethering
  • 5G coverage at no extra cost
  • Roaming still free in Europe
  • Group plans – useful for families or multiple devices

Cons

  • SIM-only – no phone contract plans
  • No major incentives, such as free streaming service subscriptions

How does SMARTY compare against other networks?

Like giffgaff and VOXI, SMARTY is characterised by a no-frills, no-fuss approach.

Its affordable and flexible SIM-only plans are some of the cheapest out there, and will suit many.

With inclusive EU roaming becoming increasingly scarce among the big networks, it’s good to see that SMARTY offers it at no extra charge.

There aren’t too many fancy extras or customer perks, but there is a good referral scheme and a discounted group plan.

And unlike major networks, SMARTY doesn’t offer phone contract plans, nor 12-month or 24-month deals.
