Why choose SMARTY?

Money off your bill for unused data

If you get to the end of the month and you're left with unused data, Smarty will take money off your next bill. For each 1GB you've not used, Smarty will deduct £1.25 from your bill.

Simple, keenly priced plans and no long contracts

Priced from £7.50 per month, Smarty's Small, Medium and Large plans all operate on a month-to-month rolling contract basis. So you're not locked in for a long time and can cancel whenever you like with 30 days' notice.

UK-wide coverage with Three's network

SMARTY uses Three's network. That means you'll get 91% 4G coverage across the UK.

Tariffs

SMARTY bills itself as the “simplest and most honest network ever” and offers just three SIM-only plans, dubbed Small, Medium and Large. All of which feature unlimited UK calls and texts.

  • Small gets you a monthly allowance of 2GB of data for £7.50 per month
  • Medium includes a 4GB monthly data allowance for £10 per month
  • Large is £15 per month and buys you a monthly allowance of 8GB

Benefits

As you might expect for a network that’s focussed on value, SMARTY doesn’t offer the kind of attention-grabbing customer incentives, such as giveaways and cheap tickets, that you get with the likes of O2 Priority.

But that’s not to say it’s not without some unique selling points. These are:

  • Money back for unused data If you’ve got any unused data at the end of the month, SMARTY will take money off your next bill. You’ll get £1.25 for each unused 1GB.
  • No long contracts SMARTY plans operate on a month-to-month rolling contract basis. So you can cancel whenever you like.
  • Extensive coverage SMARTY uses Three’s network. That means you get 91% 4G coverage across the UK.
  • Referral scheme SMARTY customers who get a friend to join them on the network will be a given a free month. And the friend gets a free month too. Persuade 12 friends to join and SMARTY will give you a whole year free.

Coverage

SMARTY's service is based on parent company Three’s network. So you’ll get 91% 4G coverage, as well as 97% 3G coverage.

Roaming

SMARTY allows you to use your monthly allowance of calls, texts and data for no extra cost in any EU destination.
