Check it yourself

Common questions

What does the WwanSvc service do?

Manages mobile broadband (GSM and CDMA) data card and embedded module adapters and connections by auto-configuring the networks. It runs C:\Windows\System32\svchost.exe (svchost.exe -k LocalSystemNetworkRestrictedRedirectionGuard -p) as LocalSystem.

Can I disable WwanSvc?

Depends on what you use. Microsoft's guidance for fixed-purpose Windows 10 and 11 IoT Enterprise devices rates it OK to disable, but adds that disabling it is not recommended for the best user experience of mobile broadband devices. If the PC has a mobile broadband data card or embedded module, leave it. Its default startup type is Manual: on the PC used for this page it was stopped.

WwanSvc is not running. Is that a problem?

Only if you use mobile broadband. Microsoft lists Manual as its default startup type, and on Windows 11 build 26300 it was stopped. Microsoft documents the netsh mbn commands for configuring and troubleshooting mobile broadband interfaces: netsh mbn show interfaces lists the mobile broadband interfaces on the system.

How do I check that it is the real service?

On build 26300 it is registered as svchost.exe -k LocalSystemNetworkRestrictedRedirectionGuard -p, runs as LocalSystem and loads C:\Windows\System32\wwansvc.dll, signed by Microsoft Windows. It depends on RpcSs and the NdisUio driver, and McmSvc and wlpasvc (Local Profile Assistance Service) listed it as a dependency.
