Hello! We have cisco 1921 router with the 4G LTE EHWIC card. We just copied working config from the old cisco 881 router with the 3G HSPA card and it doesn`t connect to ISP network. Error is:
Inactivity Reason = Activation rejected by GGSN
Also we cant chose PPP encapsulation on cellular interface there is only SLIP. Current configuration is:
...
chat-script hspa-R7 "" "AT!SCACT=1,1" TIMEOUT 60 "OK"
...
interface Cellular0
no ip address
encapsulation ppp
load-interval 60
dialer in-band
dialer pool-member 1
ppp chap refuse
ppp pap refuse
...
interface Dialer1
ip address X.X.X.X 255.255.252.0
encapsulation ppp
dialer pool 1
dialer idle-timeout 0
dialer string hspa-R7
dialer persistent
ppp chap refuse
ppp pap refuse
no cdp enable
does 4G LTE card have backward comaptibility with 3G or we have configuration error?

Hi,
for your reference, configure LTE according to below document:
http://www.cisco.com/c/en/us/td/docs/routers/access/interfaces/software/feature/guide/EHWIC-4G-LTESW.html#wp1054291
if you can attach the config i can look into it.
regards,
Shain

Cisco 4G LTE WWAN EHWIC for Cisco ISR G2. With enhanced data rates and improved latency, WWAN services are an ideal way to replace or supplement traditional wire-line services.
