4G-LTE-AU with 1941 ISR

Hi everyone:

seeking a bit help here, I have a 4G-LTE-AU installed in a 1941 ISR.

my problem is when I reload/reset router, 4G will NOT connect automatically somehow, but after I remove " dialer persistent" & "dialer idle-timeout 0" under int - dialer 1, and then re-add "dialer persistent", profile will become "active" and 4G will connect.

anyone have ideas of what cause this?

configure below:

chat-script lte "" "AT!CALL1" TIMEOUT 30

interface Cellular0/0/0
ip address negotiated
ip nat outside
ip virtual-reassembly in
encapsulation slip
dialer in-band
dialer pool-member 1
dialer-group 1
!

interface Dialer1
ip address negotiated
ip nat outside
ip virtual-reassembly in
encapsulation slip
dialer pool 1
dialer idle-timeout 0
dialer string lte
dialer persistent
dialer-group 1
!

ip nat inside source list 5 interface Dialer1 overload
ip route 0.0.0.0 0.0.0.0 Dialer1
!
dialer-list 1 protocol ip permit

line 0/0/0
exec-timeout 0 0
script dialer lte
modem InOut

**********************************************************************

and after reload the 1941, I found something interesting when router reload:

3G-Test#
%Remove Dialer Profile Configuration first
*Apr 11 00:33:49.327: %CELLWAN-2-MODEM_UP: Modem in HWIC slot 0/0 is now UP

anyone have a clue?

Try making the "idle-timeout" something like 600 (10 minutes).  Then if it sees no traffic it will hang up and try and make a call again.

I would be most tempted to use:

interface Dialer1
dialer idle-timeout 600 in
