All SMARTY plans are 30-day rolling SIM only deals bundled with unlimited UK minutes & texts, as well as Wi-Fi Calling. The network’s deals work on a prepaid basis, so there are no long-term contracts or credit checks to pass. The network also offers an unlimited data plan, in fact SMARTY’s unlimited data plan is one of the cheapest on the UK’s mobile market.

SMARTY is a unique MVNO; they offer to buy back unused data by means of a bill discount. Having said that, SMARTY’s money back scheme is only available on their Data Discount Plans. SMARTY’s Big Data Plans don’t come with this feature.

You can also start a SMARTY Group and have up to 8 plans under one account. Each SIM gets a 10% discount when they’re in a group. Their family/group mobile plans work with SMARTY’s money-back feature, allowing you to save even more.

SMARTY has a refer-a-friend program. It’s a very simple scheme; if you refer a friend, you and your friend both get a free month on SMARTY. There are no limits to how many friends you can invite to SMARTY, meaning you can keep your mobile bill free by inviting a friend a month.
