Smarty deals and incentives

Smarty only has Sim-only deals that come with no contract ranging from 4GB for £6 to unlimited data for £20 a month. All deals come with unlimited minutes and texts. 

It also have three 'data discount' deals where instead of rolling over unused data, they refund the cost of the unused data at a price of 1p per MB. 

Smarty does not have out-of-bundle costs as minutes and texts are unlimited and data is bought as an add-on.
