Hi,
Cant get 4G connection to work in a C819 router.
Get this error message in the log:
*Mar 5 07:15:54.335: %PLATFORM-4-CELLULAR_MODEM_SKU_MISMATCH: Mismatch detected between installed modem Unknown modem on SKU type C819-4G-LTE-G. Expected modem for this SKU is MC7710
Anyone know how to fix it?

Hi hencar,,
try to upgrade your firmware version to the release 3.5.29.2. let me know if you already have this version installed in your modem.

I already upgraded the router with version 15.4(3)M2 and the modem with version SWI9200X_03.05.29.02ap and it still does not work.
I got this error message when i run "sh cellular 0 all"
Warning: Mismatch detected between platform/module
and installed modem.Check system log for details

Hi Hencar,
I Just had the exact the same problem with a 1921
my router came with IOS 15.5.1T preinstalled
After reading this post I decided to downgrade the software even further so i installed 15.3.3M5(MD) which is a suggested release at the moment
The 4G card is recognized with that IOS!
Regards

Hi,
Did you downgrade to 15.3.3M5(MD) or 15.3.3M6(MD)?
That software is working for me!

Thank you,
c1900-universalk9-mz.SPA.153-3.M6 did the trick.., I thought I had allready tested but I was confused with 154-3

I have 1921 with EHWIC-4G-LTE-G. Every time I reboot my router, the 4G internet will not come up. But if I shut and unshut the cell 0/0/0, then the 4G will work.
I google it and find someone write a EEM script and it works for me.
event manager applet ResetCellOnBoot
event timer countdown name ResetIn2Mins time 120
action 1 cli command "enable"
action 2 cli command "clear interface cellular 0/0/0"
action 9 cli command "end"
action 9.9 cli command "logout"

Hi Chanhkt,
Which Version of IOS are you using?
After using c1900-universalk9-mz.SPA.153-3.M6 the Modem is working but I can't get it to connect.
I can send sms messages but it doesn't get an IP, I am using the following config.
and tried both chat scripts
chat-script lte "" "AT!CALL" TIMEOUT 60 "OK"
chat-script HSPAPLUS "" "AT!SCACT=1,1" TIMEOUT 60 "OK"
interface Cellular0/0/0
ip address negotiated
ip nat outside
ip virtual-reassembly in
encapsulation slip
dialer in-band
dialer idle-timeout 0
dialer string HSPAPLUS
dialer-group 1
async mode interactive
line 0/0/0
script dialer HSPAPLUS
no exec
I am getting the following from debug
