Following Config

cellular 0/2/0 gsm profile create 1 vpn.apn.net  chap UMTS_BACKUP_TEST #password#

chat-script UMTSDIAL "" "atdt*99#" TIMEOUT 30 "CONNECT"

!

interface Cellular0/2/0

description UMTS-Nr. +43xxxxxxxx

no ip address

encapsulation ppp

dialer in-band

dialer-group 2

dialer pool-member 207

async mode interactive

!

interface Cellular0/2/1

no ip address

encapsulation ppp

shutdown

!

interface Dialer207

description UMTS_Backup_7

vrf forwarding UMTS_APN

ip address negotiated

ip virtual-reassembly in

encapsulation ppp

dialer pool 207

dialer idle-timeout 10

dialer enable-timeout 6

dialer string UMTSDIAL

ppp chap password #password#

!

ip route vrf UMTS_APN 0.0.0.0 0.0.0.0 Dialer207

!

dialer-list 2 protocol ip permit

!

line 0/2/0

exec-timeout 0 0

script dialer UMTSDIAL

rxspeed 7200000

3G : 2 Cellular interfaces on one HWIC

Im having exactly the same issue..  I believe it has something to do with the 3G cards supporting 2 PDP contexts but i have no idea how to remove it... The thing i can think is upgrading the firmware on the card which might remove it but i dont know...

Can anyone help ?
