UK Mobile Networks
Compare coverage, reviews, and deals from all UK mobile operators. From the three infrastructure owners to budget-friendly virtual networks.
The major networks
EE, Virgin Media O2 and VodafoneThree own the UK's mobile infrastructure - every other operator runs on one of their signals. Vodafone and Three merged in 2025 and are combining into a single network, but still sell as separate brands.
EE
Users who want the fastest, most reliable network in the UK and are willing to pay a premium for cutting-edge 5G technology and bundled entertainment perks.
O2
Customers who want a well-rounded network with excellent loyalty perks, free EU roaming, and competitive pricing without paying EE's premium.
SIM plans from £7.00/mo
Three
Budget-conscious heavy data users who want affordable unlimited data and the fastest 5G speeds, and who are comfortable with a 100Mbps cap unless they step up to a full-speed tier.
Vodafone
Tech-forward users who want the UK's biggest network footprint following the Three merger, 5G+ standalone coverage at no extra cost, and inclusive European or worldwide roaming - provided they step up to a Plus or Premier plan.
Virtual networks (MVNOs)
These networks piggyback on one of the major operators above. They often offer more flexible plans or specialised features while using the same reliable signal.
