How NetScan works

01

Postcode geometry

We parse your postcode into its UK postcode area & district, then resolve population density, urban / rural classification and regional terrain.

02

Per-operator signal model

Each of EE, Vodafone, O2 and Three has a distinct signal fingerprint — strengths in cities, motorway corridors and rural notspots. We score all three bands.

03

Crown the winner

An overall score (weighted toward 5G & 4G) ranks the four UK operators. The strongest network for your postcode wins.

04

Surface the deals

We pull the top contract deals from the winning carrier — iPhone, Samsung Galaxy, Pixel and more — so you sign up where the signal is best.

FAQ

How does NetScan UK determine the best mobile network for my postcode?

NetScan UK analyses each operator's published 5G / 4G / 3G performance for your postcode area, weighting urban / rural density and known coverage strengths to rank EE, Vodafone, O2 and Three for your specific address.

Are the phone deals up to date?

The curated dataset reflects representative UK 2026 pricing for flagship and mid-range phones across EE, Vodafone, O2 and Three. Always confirm the final price on the operator's own site before signing a contract.

Is NetScan UK free to use?

Yes — free, open-source, no sign-up, no tracking. All processing happens in your browser.

Why do I see different rankings for nearby postcodes?

Coverage varies block by block in built-up areas. NetScan reads the postcode district, not just the area code, so a city-centre result can differ from the suburb just a mile away.
