Dial Command = ATDP
FlowControl = NOFLOW

'ATDP' is 'pulse dialling'; as far as I know this is not supported by cell phones. You should be using 'ATDT' (tone dialling).

The 'flow control' should be set to hardware handshake.

You may also need to set the username and password - any string will do since they are not actually checked.

Baud = 19200
SetVolume = 0

Init1 = ATZ
Init3 = ATM0
FlowControl = CRTSCTS
[Dialer Vodafone]
Username = web
Password = web
Phone = *99***1#
Stupid Mode = 1
Init1 = ATZ
Inherits = Modem0

The 'hangup' suggests that there may have been a long wait during the negotiations and pppd decided to give up. You need to look at the pppd messages in /var/log/messages:

grep ppp /var/log/messages | less

The messages may give you a better idea what went wrong. If all it says is "hung up" then you need to set a longer timeout for the pppd negotiation. You *should* be able to do that via wvdial. Also use minicom to check the signal quality (AT+CSQ); sometimes if the signal quality is poor the modem will connect and disconnect frequently.
