I have been trying for ages to use the Orange  ZTE AC2726 USB EVDO Modem on openSuSE Linux 11.3 Gnome to connect to the internet.

have edited the /etc/wvdial.conf file as follows

[Dialer Defaults]
Modem = /dev/ttyUSB0
Baud = 57600
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 =
Area Code =
Phone =#777
Username =card
Password =mypassword
Ask Password = 0
Dial Command = ATDT
Stupid Mode = 1
Compuserve = 0
Force Address =
Idle Seconds = 300
DialMessage1 =
DialMessage2 =
ISDN = 0
Auto DNS = 1

When I execute the wvdial command on the terminal the following error appears

joey-suse:~ # wvdial
--> WvDial: Internet dialer version 1.60

The /etc/resolv.conf file has the DNS addresses as below

nameserver 212.49.70.22

nameserver 212.49.70.23

How do I resolve this and connect to the internet?

Thanks.
