SMARTY SIM only deals
SMARTY is a SIM‑only mobile brand run by Three UK, offering month‑to‑month plans without credit checks or long-term contracts. Coverage is powered by Three’s network providing 99% UK outdoor population coverage and growing 5G access at no extra cost.
Does SMARTY run a credit check when I sign up?
No. Because SMARTY plans are rolling one-month contracts paid in advance, there's no credit check to join.
That makes it a good option if you're building or rebuilding your credit history, or simply want the freedom to cancel or change your plan at any time.
What happens to unused data on a SMARTY plan?
On SMARTY's smaller capped plans you're automatically refunded for data you don't use, knocking money off your next month's bill.
On unlimited plans there's nothing to roll over, but you're never charged more than the fixed monthly price, and you can switch between allowances each month to match your usage.
