Why choose Smarty?

Smarty's pricing is consistently among the most competitive for data heavy plans in the UK. There are no contracts, no credit checks, and no mid contract price rises the price you agree to is the price you pay. Plans are monthly and can be changed each cycle. Smarty runs on Three's network, which is strong for data and 5G in urban areas but patchier in rural locations worth checking your coverage before committing. For anyone who wants maximum data for minimum spend without a long term commitment, Smarty is a standout option.

MVNO

Smarty is owned and operated by Three UK, which means it runs on Three's own network infrastructure. Coverage mirrors Three directly. The benefit is that you get Three's data performance without Three's direct pricing Smarty consistently undercuts Three on equivalent plans.

eSIM and WiFi Calling

Smarty supports eSIM on compatible phones, allowing you to join and activate digitally without waiting for a physical SIM. WiFi Calling is also included on eligible devices, which helps with call quality in areas where indoor Three signal is weak.
