SMARTY information
Radical simplicity on Three's masts: one-month plans, plain terms, and the cheapest honest audition of Three's network anywhere.
Common questions
What makes SMARTY different?
Deliberate simplicity: rolling one-month plans with plain terms — and because there's no fixed contract, none of the mid-contract price-rise machinery either. It suits anyone who wants a fair monthly deal without negotiation or lock-in.
What coverage will I get?
Three's — SMARTY owns no masts. Strong high-street 5G, historically thinner deep indoors and deep rural; the full picture is on the Three information page, and the check method is in the coverage guide. Where Three is weak at your address, no plan price fixes it.
Is SMARTY good for testing Three's network?
It's arguably the cheapest serious audition of Three's masts anywhere — one month, plain terms, walk away freely if the coverage disappoints.
Does SMARTY have every Three feature?
No — hosted brands trail the host's feature set. Confirm Wi-Fi Calling, eSIM and 5G access for your handset through SMARTY's official pages rather than assuming parity with Three.
Who handles my support?
SMARTY's own channels, app-first — never Three's helpdesk, despite the shared masts.
