Problems with Cisco 887 3G functionality

We have a question about the configuration of the 3G functionality on the cisco 887 router. The 3G connection should be the primary connection, because we don't have a direct internet connection. We make use of a data card of KPN NL. On the internet we found some information about the configuration of the 3G module, but won't get a 3G connection. If we look to the gsm profiles we see that the profile is still inactive. Can someone help me with the configuration of the 3G functionality and tell me how to activate the gsm profile?

Make sure the SIM card is not locked with a pin code, you can check from the router with
sh cell 0 security

If the output contains "SIM Status = Locked" then type cellular 0 gsm sim unlock [current pin code] to unlock the card.

When you are sure there is no PIN, you can use the following template:
cellular 0/0/0 gsm profile create 1 office.vodafone.nl ipv4 pap vodafone vodafone

interface Cellular0/0/0
ip address negotiated
ip nat outside
ip virtual-reassembly
encapsulation ppp
dialer in-band
dialer string gsm
dialer-group 1
async mode interactive
ppp authentication pap callin
ppp chap refuse
ppp pap sent-username vodafone password 0 vodafone
end


dialer-list 1 protocol ip list 1
