Who are SMARTY?

SMARTY exists because there’s a better way to do things. Low costs, straightforward plans, transparent pricing and flexible deals. They even give money back for the data you don’t use. They’re on a mission to put the trust back into our industry by doing things properly. Simple, honest, mobile. No minimum contract, no credit checks and no surprises at the end of the month. Pay in advance and enjoy the flexibility. SMARTY is powered by Three’s strong and reliable 3G network. It covers 97% of the population, with fast speeds for browsing, gaming, downloading and emailing. You’ll also be able to enjoy 4G with SMARTY, where available.

Slash your student bills!

Student life can be so expensive! This is where SMARTY comes in to help you with your savings. It's only from £5 = the base cost of SMARTY data discount plans (unlimited standard calls, texts and running the network). The rest is simply for data. At the end of each month, they take the data you haven’t used and discount your next plan - at a rate of £1.25 per GB. So for 3GB of unused data, you’ll get £3.75 off your next month. They even calculate using remaining MBs, not GBs. Finally, save up for your students nights with your SMARTY plan.
