eRedCap (3GPP Release 18) will not operate on 5G Non-Standalone (NSA) networks. NSA – which accounts for the majority of current consumer 5G coverage – runs a 4G LTE core (EPC) with 5G NR radio added as a secondary carrier. eRedCap’s power saving mechanisms and reduced capability signalling require the 5G Core (5GC), which only a 5G Standalone network provides.
5G SA vs 5G NSA – The Key Distinction
When an operator announces “5G coverage”, they are almost certainly referring to 5G NSA in most of that coverage area. 5G SA is a separate, later deployment that requires the operator to have upgraded their core network to the 5G Core architecture. The two are not interchangeable for eRedCap devices.
The practical check: eRedCap devices will need SIM provisioning and APNs that route to 5G SA cells specifically. Coverage in a given postcode for 5G NSA does not guarantee eRedCap device connectivity at that location.
UK Operator Status
EE has live 5G SA infrastructure. EE was among the first UK operators to deploy SA and has been running 5G SA in key cities since 2023-2024. EE 5G SA coverage is expanding. See the EE eRedCap coverage page for current status.
Vodafone has live 5G SA infrastructure. Vodafone UK has committed to 5G SA as its strategic network direction with coverage building through 2025-2026. See the Vodafone eRedCap page.
Three UK is building 5G SA capability as part of its network modernisation programme.
O2 / VMO2 is developing 5G SA infrastructure with commercial SA offerings in development.
