About SMARTY
SMARTY is a UK mobile virtual network operator (MVNO) running on Three's extensive 4G and 5G network, offering straightforward SIM-only deals with no long-term contracts. Operated by Hutchison 3G UK Limited, SMARTY was designed to provide cheaper, simpler mobile plans than traditional networks. What sets SMARTY apart is their unique "pay for what you use" approach - customers who don't use their full data allowance receive a credit on their next month's bill, making it the only UK network offering this fair-use benefit. All plans include unlimited calls and texts, with 5G access included at no extra cost. SMARTY offers flexible 30-day rolling plans ranging from data-capped options (30GB for £10, 60GB PAYG) to unlimited data for £20 per month. No credit check is required, making SMARTY accessible to everyone. EU roaming is included with up to 12GB data abroad, plus the network supports eSIM, 4G calling (VoLTE), and WiFi calling. With access to Three's network covering 99% of the UK population (plus Vodafone network via the merger), SMARTY delivers reliable coverage at competitive prices.
