mode
(LTE)Sleep In this case, the current consumption of module
will be reduced to the minimal level.
In sleep mode, the module can still receive paging
message and SMS.
(LTE)
Idle
Software is active. Module is registered to the
LTE network, and the module is ready to
communicate.
(LTE) talking Connection between two subscribers is in progress.
