which network does sky mobile use

Sky Mobile uses the O2 network for its mobile services. This means that Sky Mobile customers get coverage wherever O2 has a network signal, including 2G, 3G, 4G, and 5G. Sky Mobile operates as a Mobile Virtual Network Operator (MVNO) that hires the mobile spectrum from O2, providing customers with the same coverage and network infrastructure as O2 users. The 5G coverage Sky Mobile offers matches that of O2's 5G availability in the UK. Sky Mobile's network speeds and coverage are very similar to O2's, ensuring broad coverage in populated and many rural areas.
