No network wins Twickenham on coverage. All four are within 1 point of each other in Ofcom's measurements, across 2,192 addresses sampled in 107 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 Twickenham as a whole.
Ranked by Ofcom's overall score: O2 100, Three 100, Vodafone 100, EE 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 Twickenham are Ofcom's own measurements, taken from the Ofcom Mobile Coverage API (May 2025 data) across 2,192 addresses in 107 postcodes. They describe outdoor signal at sampled addresses across the whole of Twickenham; signal inside a specific building, and on a specific street, can differ from the area figure.
Every network clears the bar in the TW 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.
