Help to troubleshoot a 3G connection.

Question

Hello!
I need help to troubleshoot a 3G connection.
It's a CISCO2921/K9 with UC license and a 3G Interface.
I used the manual to make the configuration, step by step, I can send and receive SMS by 3G network, and connect, take a IP, DNS etc, but I don't able to ping or send and receive data with the 3G connection.
See the information:
show ip int br
Interface                  IP-Address      OK? Method Status                Protocol
Embedded-Service-Engine0/0 unassigned      YES NVRAM  administratively down down    
GigabitEthernet0/0         192.168.50.1    YES NVRAM  up                    up      
GigabitEthernet0/1         192.168.6.253   YES DHCP   up                    up      
GigabitEthernet0/2         unassigned      YES NVRAM  administratively down down    
Cellular0/0/0              unassigned      YES NVRAM  up                    up      
Cellular0/0/1              unassigned      YES unset  down                  down

NVI0                       192.168.50.1    YES unset  up                    up      
I have a radio ISP connected on interface G0/1 and my internal network is connected in G0/0 on a Layer 3 Switch.
