Sleep mode2): indicates that the module enters the low power consumption state. In this state, the peripheral
interface of the module is disabled, but the radio frequency function is normal. The module will exit the sleep
mode when there is an incoming call or an SMS message, and will re-enter the sleep mode when the incoming
call and voice end.
Idle mode3): indicates the status of the module when the module is functioning properly and there is no data
service.
Operating mode4) current indicates the operating current of the module when there is data communication. In
operating mode4), only an example of the current in LTE mode is provided. For details about the current in non-
LTE modes, see the N58 current test report.
