The +CEMODE command is defined in 3GPP TS 27.007 (e.g. in section 10.1.28 in v11.0.0). This command allows querying or updating the current UE mode, as well as checking the supported modes. We implement support for loading the current mode and updating it. It is assumed that the device does any additional operation needed by the setting update, e.g. un-registering from CS when selecting an EPS-only mode.
