Ofcom measures EE, O2, Three and Vodafone within 4 points in Canterbury (CT), 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 Canterbury on coverage. All four are within 4 points of each other in Ofcom's measurements, across 814 addresses sampled in 49 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 Canterbury as a whole.
Ranked by Ofcom's overall score: O2 100, Three 99, Vodafone 99, EE 96. The spread between best and worst is 4 points, 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 Canterbury are Ofcom's own measurements, taken from the Ofcom Mobile Coverage API (May 2025 data) across 814 addresses in 49 postcodes. They describe outdoor signal at sampled addresses across the whole of Canterbury; signal inside a specific building, and on a specific street, can differ from the area figure.
Every network clears the bar in the CT 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 4-point coverage gap. Check your own postcode above first: indoor signal varies street by street even where the area figures match.
