I've tried that, i can't seam to set the "FASTENUMEN" setting to "0":

AT!CUSTOM?
!CUSTOM: 
             GPSENABLE		0x04
             GPSSEL		0x01
             IPV6ENABLE		0x01
             SIMLPM		0x01
AT!ENTERCND="A710"
OK
AT!CUSTOM="FASTENUMEN",0
OK
AT!CUSTOM?
!CUSTOM: 
             GPSENABLE		0x04
             GPSSEL		0x01
             IPV6ENABLE		0x01
             SIMLPM		0x01
             USBSERIALENABLE	0x01
             SINGLEAPNSWITCH	0x01


OK
AT!RESET
OK

Also to be completely honest i don't really feel comfortable setting things i don't really understand. From what i understand, since the command AT!PCINFO? outputs

State: Online
LPM voters - Temp:0, Volt:0, User:0, W_DISABLE:0, IMSWITCH:0, BIOS:0, LWM2M:0, OMADM:0, FOTA:0
LPM persistence - None

and not State: Low Power Mode, The Modem is probably NOT in "Airplane Mode", and therefore all of this should not be needed in my case, could be completely wrong though!

If anyone understand this better then i do, please let me know!
