At SMARTY we like to keep things simple. That’s why we’re changing the name of our add-ons to make it clearer what they can be used for.

All of our SIM plans come with unlimited calls and texts to standard UK landlines, freephone numbers and standard UK mobiles.

But when you want to call a number that’s chargeable – such as premium numbers starting 084 or 087 – make international calls, or call and text from a non-included roaming destination, you will need an add-on because this service is ‘out of plan’.

Our add-ons essentially give you an allowance to make those chargeable calls.

To try and make the process simpler, we’ve renamed our ‘Cash add-ons to ‘Out of plan add-ons’. In the same way, your ‘Cash balance’ will now be your ‘Out of plan balance’.

Purchasing an ‘Out of plan add-on’ is easy. Head to smarty.co.uk/dashboard, and click on 'View details' under Account balances and credits. Click on 'Manage add-ons' and follow the onscreen instructions.

You can also buy an add-on through our SMARTY App, by going to the Dashboard screen and selecting Add-ons at the top of the page.

If you’d like to find out more about what numbers may be chargeable, we have a great article in our help section. Plus, if you’d like more information on international calling and roaming it can be found here.
