Hello TJ81,

all profiles are inactive and the following line say

>> Current Service Status = No service

I would say that LTE is not currently available in your area.

You should try to configure the device to use a slower/older technology like 3G or even GSM.

There was a similar thread in the last days and the original poster of that thread solved in this way.

Hope to help

Giuseppe

TJ81 · ‎06-23-2019

Hi Giuseppe,
Thank you for the information. But the area was covered under 4G. Also I was check on mobile phone on same carrier and i'm getting 4G on the same place where the router was placed.

Giuseppe Larosa · ‎06-23-2019

Hello TJ81,

ok there is 4G service.

The next step I would check is the chat script LTE you are using.

Check in the mobile provider support web pages what chat script they would expect to receive from an LTE modem.

Edit:

I have checked the configuration I had done for a customer using a C819 few years ago.

I report on the following lines the most meaningful sections:

chat-script hspa-R7 "" "AT!SCACT=1,1" TIMEOUT 60 "OK"

interface Cellular0
ip address negotiated
ip access-group 125 in
ip nat outside
ip inspect CLASSIC_FW out
ip virtual-reassembly in
encapsulation slip
dialer in-band
dialer string hspa-R7
dialer-group 1
>>async mode interactive
!

And the async line config:

line 3
exec-timeout 10 10
script dialer hspa-R7
modem InOut
no exec
transport input all
rxspeed 21600000
txspeed 5760000

Hope to help

Hi George & Larosa

Thank you for the suggestions. Still no luck I'm getting following on debugging

Router#debug dialer

Dial on demand events debugging is on

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:

Giuseppe Larosa · ‎06-26-2019

Hello TJ81,

I would go back to your original LTE chat script as now the debug shows a worse scenario it simply time out and the cell interface does not get any IP address.

keep the async mode interactive command in cell interface and the other commands under the corresponding line.

Edit:

I have seen in the other thread that you have solved and the issue was the SIM taken from a vodafone CPE.

Nice to know that it is not possible to re-use those SIMs in other routers.

Hope to help

Giuseppe
