Coverage analysis — RG18
No network wins Reading on coverage. All four are within 3 points of each other in Ofcom's measurements, across 101 addresses sampled in 6 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 Reading as a whole.
Ranked by Ofcom's overall score: O2 100, Vodafone 100, EE 98, Three 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.
Why O2 for RG18?
O2's 5G rollout in Reading is among the strongest nationally, covering 100% of premises in the RG18 district. For anyone streaming video, gaming on mobile, or relying on a mobile hotspot at home, this level of 5G penetration makes a real difference to day-to-day speed.
The runner-up in RG18 is Vodafone at 100/100 (100% 5G / 100% 4G). It is a close contest — both operators deliver strong coverage in RG18, and your choice may come down to tariff, handset preference, or existing contract.
Choosing a network in Thatcham
Every network reaches Thatcham, Cold Ash, Chieveley and Bucklebury to the same standard in Ofcom's data (within 3 points), so coverage cannot pick one for you here — price and contract length can. Compare what each is charging, then check the exact street you live on before you commit, because indoor signal still varies where the area figures match.
