On my ¨wvdial.conf¨, type like this

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = *99#
New PPPD = yes
Modem = /dev/ttyUSB0
Username = XXX
Password = XXX
Baud = 9600

[D-cat]

So all know, this is a cellular phone connected to T-mobile service. *99# is the dial code to T-mobile's Internet service that takes minutes off your plan... The unlimited plan number is *99***2# (last I checked).

If you're connecting then it's dropping, it sounds like a authentication error on their end. I'd consult T-mobile's customer service to make sure your settings are correct and your service is built correctly. We want to make sure the problem really is on your end and not their's before we go ballistic here.
