Why we love SMARTY

SMARTY mobile

Cut costs with a SMARTY group plan

If you live with friends or family who also opt for SMARTY as their mobile network, there’s a quick and easy way for you both to save. Put all your households plans together into a SMARTY group plan and every member of the group gets 10% off their monthly rates. Group plans can go as large as eight people, making it a great choice for student sharers and families alike.

Get money back with a SMARTY data rollover

Anyone eager to pay even less for their monthly data has a thrifty alternative at SMARTY thanks to their data rollover plans. Designed for those who use minimal amounts of data, rollover plans range from 1GB to 3GB of data every month, with up to 35% of each monthly payment being paid back depending on how much of that data is used each month. Customers can get up to £3 back each month, making it possible for spendthrifts to save as much as £30 a year on an already affordable mobile plan.

No need to change your number at SMARTY

With SMARTY focusing on offering the lowest stress as well as the lowest priced mobile plans in the UK, customers don’t even need to worry about switching up to a new number when coming from other providers. There’s no credit check needed either, making it literally as easy as entering your details.

SMARTY money-back guarantee

To give every customer absolute peace of mind when choosing SMARTY, the brand provides a 14-day window for customers to cancel their mobile plan with no questions asked. Those cancelling who haven’t activated their SIM cards can cancel easily on the ‘Money Back Guarantee’ page, whilst those who have need only start an online chat with customer service to get their cancellation started.

SMARTY contact details

There’s a great brand in town: SMARTY

SMARTY provides a freer alternative to your traditional mobile retailer, replacing lengthy contracts with affordable data plans and no commitments. With SIM only deals and unlimited minutes and texts guaranteed, a SMARTY discount code is simply one of the many ways you can get top value from your monthly package. Designed to offer ultimate flexibility at an unbeatable price, there’s no stress, no bother and barely any expense when you opt for a SMARTY mobile plan.

Refer a friend to SMARTY

To add to the many other ways in which SMARTY keeps their costs low, the brand offers an additional incentive to customers willing to spread the word. Should you know any friends or family looking to switch up their mobile provider, send them a referral to SMARTY and they’ll be guaranteed to get their first month free. In return, you can expect to receive all your next month’s data, texts and minutes without having to pay a penny.

SMARTY SIM Only Deals

The cornerstone of the company's success, SMARTY SIM only plans offer up all the essentials needed to get the most from mobile. Whether you need 5G for Google Maps, to stream music or simply catch up with your favourite podcast, a SMARTY voucher will secure you the data you need whilst barely putting any strain on your bank balance. Data options are available from 4GB all the way up to unlimited, making it easy for you to adjust your plan to match your monthly usage.
