Thanks waterhead, I installed kmod-option and after installing I used wvdial to see if I would be able to connect and this is what happened

[root@washi serial]# wvdial tmobile
--> WvDial: Internet dialer version 1.54.0
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ

--> Carrier detected. Starting PPP immediately.
--> Starting pppd at Mon Mar 8 22:32:00 2010
--> pid of pppd: 4643
--> Using interface ppp0
--> local IP address 10.221.9.22
--> remote IP address 10.64.64.64
--> primary DNS address 149.254.192.126
--> secondary DNS address 149.254.201.126

but when I try to ping google I get a message saying unknown host and I cant open any website in firefox.

Well, you are about 95% the way there. You need to edit your /etc/resolv.conf file to tell it what DNS server to use for name resolution, so that things like Google are resolved into the correct IP address, such as 74.125.95.104 (which is one of the addresses associated w/ Google). Here is an example of /etc/resolv.conf that you can use:

nameserver 199.45.32.37
nameserver 199.45.32.40

If you execute the command ifconfig you should see the inet address assigned to your PPP connection. From that, you might be able to determine what their DNS server may be, but in any caes, the nameserver entries shown above will work just about everywhere as they are for top-level internet domain name servers.

Ok. I looked at your posting again. It says what your DNS servers for the connection should be, so your /etc/resolv.conf should contain these two lines:

nameserver 149.254.192.126
nameserver 149.254.201.126

Yes it is a USB modem.

For me its the same with centos not creating a USB tty so i use
/sbin/modprobe usbserial vendor=0x19d2 product=0x0031

Thank you for posting the details on how you got it to work.
