Ofcom measures EE, O2, Three and Vodafone within 1 point in Milton Keynes (MK), so no network wins here on coverage. Pick on price — then check your own postcode, because indoor signal still varies street by street.
No network wins Milton Keynes on coverage. All four are within 1 point of each other in Ofcom's measurements, across 2,007 addresses sampled in 106 postcodes. On a difference that small, EE, O2, Three and Vodafone will all work here — so choose on price, contract length and roaming, not on a coverage map. Coverage only becomes the deciding factor once you leave built-up areas, and it still varies street by street indoors: check your own postcode below to see the measurement for your address rather than for Milton Keynes as a whole.
Ranked by Ofcom's overall score: O2 100, Vodafone 100, EE 99, Three 99. The spread between best and worst is 1 point, which is inside the margin where a coverage figure stops being a useful tiebreak. Ofcom's data describes outdoor signal across sampled addresses; it cannot tell you how any of them behave inside your own building.
These scores for Milton Keynes are Ofcom's own measurements, taken from the Ofcom Mobile Coverage API (May 2025 data) across 2,007 addresses in 106 postcodes. They describe outdoor signal at sampled addresses across the whole of Milton Keynes; signal inside a specific building, and on a specific street, can differ from the area figure.
Every network clears the bar in the MK postcode area, so the honest advice is to stop comparing coverage maps and start comparing prices — the difference between the cheapest and dearest plan will dwarf a 1-point coverage gap. Check your own postcode above first: indoor signal varies street by street even where the area figures match.
