This guide applies to Vera 3 units with firmware versions older than 1.5.600.
Instructions
Connect to the unit by ssh as explained here, then follow these steps:
1. Plug in USB Modem in Vera
2. Check if the modem is insterted correctly and that vera can see it .
gcom info /dev/ttyUSBx | x = 0 or 1
3. In /etc/config/network add the following :
config 'interface' 'wan'
option 'ifname' 'eth0.2'
option 'device' '/dev/ttyUSB0'
option 'apn' 'internet'
option 'service' 'umts'
option 'proto' '3g'
If the modem has a PIN code add it :
option 'pincode' '1234'
If the modem requires an username and password set it :
option username yourusername option password yourpassword
Save and exit
4. Check 3G chatscripts ( they are used for the method of connection )
cat /etc/chatscripts/3g.chat
ABORT BUSY
ABORT 'NO CARRIER'
ABORT ERROR

TIMEOUT 10
"" "AT+CSQ"
OK "ATE1"
OK 'AT+CGDCONT=1,"IP","$USE_APN"'
SAY "Calling UMTS/GPRS"
TIMEOUT 30
OK "ATD*99***1#"
CONNECT ' '
Settings should be like the ones above.
5. Restart network (be sure to on lan conected to it , not by wan !! IT will not show debugging info )
/etc/init.d/network restart
BRIDGE ADDBR : brctl addbr br-lan
BRIDGE ADDIF br-lan eth0.1
BRIDGE ADDIF : brctl addif br-lan wlan0
BRIDGE DELIF : brctl delif br-lan
Configuration file: /var/run/hostapd-phy0.conf
Using interface wlan0 with hwaddr 00:0e:8f:72:a3:36 and ssid 'na900_31000000'
BRIDGE DELIF : brctl delif br-lan wlan0
BRIDGE ADDIF : brctl addif br-lan wlan0
6. Watch logread with the following parameters :
logread -f | grep local2.info
It should be like this
Feb 15 04:18:15 MiOS_31000000 local2.info chat[11495]: abort on (BUSY)
Feb 15 04:18:15 MiOS_31000000 local2.info chat[11495]: abort on (NO CARRIER)

Feb 15 04:18:15 MiOS_31000000 local2.info chat[11495]: OK
7. Check ifconfig
3g-wan Link encap:Point-to-Point Protocol
inet addr:172.22.205.5 P-t-P:10.64.64.64 Mask:255.255.255.255

collisions:0 txqueuelen:3
RX bytes:1025131 (1001.1 KiB) TX bytes:717822 (700.9 KiB)
8. Start and stop 3G
To stop it :
ifdown wan
To start it :
ifup wan
If you encounter any issues you can check the logs at :
logread -f | grep local2.info
Possible issues :
1. Not being able to connect to the modem (on /etc/init.d/network restart -> no such device )
Cause : USB port miss-configuration
Resolution :
Type the code below until the USB modem is detected
gcom info /dev/ttyUSBx
Then update the option 'device' '/dev/ttyUSB0' in
/etc/config/network
2. 3G (error) PIN code incorrect :
Be sure to set the PIN if it has one, or if it doesn't have one dont set it at all.
