Comparing EE, Vodafone, O2 and Three across 5G · 4G · 3G for the Bristol (BS) postcode area. Use the scanner below to check your exact postcode.
Ofcom measures EE, O2, Three and Vodafone within 3 points in Bristol (BS), 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 Bristol on coverage. All four are within 3 points of each other in Ofcom's measurements, across 1,478 addresses sampled in 85 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 Bristol as a whole.
Ranked by Ofcom's overall score: O2 100, Vodafone 100, Three 98, EE 97. The spread between best and worst is 3 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 Bristol are Ofcom's own measurements, taken from the Ofcom Mobile Coverage API (May 2025 data) across 1,478 addresses in 85 postcodes. They describe outdoor signal at sampled addresses across the whole of Bristol; signal inside a specific building, and on a specific street, can differ from the area figure.
Every network clears the bar in the BS 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 3-point coverage gap. Check your own postcode above first: indoor signal varies street by street even where the area figures match.
