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.

Smarty runs on Three's network and has built its reputation around simple, rolling monthly plans with no long-term contract and no credit check required, making it an accessible option for a wide range of switchers, including those who might struggle to pass a traditional credit check with other providers.

1. Smarty's rolling, no-commitment model

Unlike many SIM-only brands that offer better pricing for longer commitments, Smarty is built around monthly rolling plans as standard, letting you change or cancel with a month's notice at any time without penalty.

2. No credit check required

Smarty's plans typically don't require a credit check, which can make it more accessible than providers requiring one, particularly for younger switchers or anyone with a limited credit history.

3. Data rollover

Smarty has generally offered rollover for unused data into the following month, adding value similar to other flexible SIM-only brands.

4. Smarty and Three's network

Since Smarty runs over Three's infrastructure, coverage should broadly match Three's own network. Check Three's coverage specifically for your area before switching.

5. Comparing against other Three-network brands

Compare Smarty against Voxi, another budget brand running on Three's network family, to see which offers better value and features for your usage.
