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 examples of the current in LTE, 5G NR, and V2X modes is

provided. For details about the current in other modes, see the A590 current test report.
