Best mobile network in PR9 Preston postcode district

Cross-referencing EE, Vodafone, O2 and Three using Ofcom 2024 data, EE is the clear winner in Preston. In this mixed urban-rural area, EE achieves an overall coverage score of 83/100 — driven by good 5G coverage (66%) and rock-solid 4G at 100%. 5G and 4G scores are closely matched, reflecting a mature, stable network.

EE clearly leads Three by 7 points overall. While Three reaches 54% on 5G and 99% on 4G in Preston, it falls short of EE's combined performance across all bands. O2 and Vodafone round out the field at 73 and 72 respectively.

EE has made solid 5G inroads across Preston, reaching 66% of premises in PR9. While not blanket coverage, most streets and town centres are covered — and 4G fallback at 100% keeps reliability high throughout.

The runner-up in PR9 is Three at 76/100 (54% 5G / 99% 4G). The margin is noticeable but not enormous. EE edges ahead on 5G depth; if your plan is with Three, 4G performance should still be solid.
