Description
AT+UBMCONF?
+UBMCONF: 1
OK
Check the +UBMCONF <networking_mode>, which must be
1 = Router mode (as the factory-programmed value) for the
context activation procedure herein described.
AT+CFUN=4
OK
Set the module in airplane mode. The module will deregister
from network and both RF Tx and RF Rx will be disabled.
AT+CGDCONT=1,"IP","ibox.ti
m.it"
OK
Define a PDP context with preferred APN: in this example,
the “ibox.tim.it” APN is selected.
AT+UCGDFLT=1,"IP","ibox.ti
m.it"
OK
Define the initial PDP context with preferred APN. This will
be activated only if the module registers to an LTE network.
AT+CFUN=1
OK
Set the module to full functionality. The module starts the
automatic network registration.

+COPS: 0,0,"I TIM",7
OK
Check the +COPS <AcT> and act accordingly:
If
<Act> = 7 (LTE, as it is in this example)
Then
no further action is needed
Else
activate the context with +CGACT as following:
