Airport SIM & eSIM Prices

EE has the strongest coverage once you head into the Highlands or the Borders, which matters if a Scotland trip goes beyond Edinburgh. No ID is required to buy or activate a UK prepaid SIM.

Usually the best value large-data plan and, thanks to its 'Go Roam' feature, often free to use in several other European countries too — handy if Edinburgh is one stop on a wider trip. Signal thins out noticeably once you leave the central belt.

Reliable coverage in and around Edinburgh with quick app-based activation. EU roaming data allowances tend to be smaller than the UK bundle, worth checking if travelling on to continental Europe afterwards.

A budget SIM-only brand on O2's network with cheap 'Goodybag' data plans, best ordered a week or so before travelling since the free SIM arrives by post rather than being available instantly.

A solid mid-range option with decent city coverage and simple top-up bundles, and the network that giffgaff and several other budget brands run on if you'd rather deal with the parent company directly.
