Uswitch Awards Best SIM-Only Value for Money 2022

No speed restrictions

Smarty plans don't have any speed restrictions.

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.

No credit checks

You can sign up to a SMARTY without the need for any credit checks.

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 5G in a wide range of UK locations as well as 91% 4G coverage.

Speed

Smarty uses Three's network which is averages at 22.55Mbps.

Roaming

SMARTY’s roaming scheme is divided into two plans:

With SMARTY you can use your mobile to call, text and get online while travelling abroad.

Travelling in the EU

Everything works like home. Data comes out of your monthly allowance or data add-ons. Calls and texts are unlimited. You need a cash add-on to make calls and texts from EU countries to the rest of the world.

Travelling outside the EU

You need a cash add-on for data, calls and texts for countries outside the EU. Top up your cash balance, then just pay as you go.

Customer service

SMARTY doesn’t offer customer service telephone support. However, customers can contact support by visiting the SMARTY site and starting a web chat.

The web chat service is available from 8am to 8pm every day, except Bank Holidays.
