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

Standard UK landlines start with 01, 02 and 03, freephone numbers start with 080 and standard UK mobile numbers start with 07. 

Calls to services numbers are chargeable, so you'll need to buy a cash add-on before dialling any numbers that start with 084 or 087, plus any non-emergency numbers like 101.

How to get an add-on

Adding credit to your SMARTY balance is very straightforward. Either use the link in the notification text message or go to, log in to your SMARTY dashboard, click on ‘Buy cash add-on’ and follow the instructions.

You have the choice of buying an add-on worth £5, £10 or £15.

What happens to a cash add-on if you leave SMARTY?

If you're looking to leave SMARTY and you've still got unused credit from an add-on, we won't be able to give you a refund.

However, our add-ons never expire so you can use them at any time.
