There are two ways you can save money off your next SMARTY plan:
At the end of each month, we take the data you haven’t used and discount your next plan - at a rate of £1.25 per GB, except for the unlimited plan, where a discount isn't applicable.
So for 3GB of unused data, you’ll get £3.75 off your next month. We even calculate using remaining MBs, not GBs.
Converting your cash balance
If you have money in your cash balance, you can convert that into a reduction off your next months plan.
For example, you go on holiday and top up your cash balance by £10 to use your phone abroad. You come back and you have £5 left on your balance. You can convert this into money off and we will take it off your next plan.
