Coverage and network
Smarty uses the Three network rather than its own infrastructure, and it reports 4G and 5G coverage across most of the UK population. As with any mobile provider, it is worth checking signal strength in your area before signing up.
Plans and pricing
Smarty’s SIM-only plans include unlimited minutes and texts, with data allowances depending on the plan you choose. It also offers a social tariff for eligible customers, including unlimited data for £12 per month.
Roaming
All Smarty SIM plans include 12GB of free EU roaming. This is useful for occasional travel, though destination coverage should still be checked carefully because some countries are excluded.
Support
Smarty is an online-only provider, so there are no shops or in-person support locations. Help is available through its website, live chat, and email support.
Final verdict
Smarty is a solid choice if you want affordable SIM-only mobile service with flexible contracts and straightforward pricing. It is best suited to users who are comfortable managing everything online and want value without extra complexity.
