Yep, the Vodafone Connect cards work quite well.
When I started to use the service it seemed to be pretty sluggish. In
particular it appeared to be spending most of it's time hung on DNS
lookups. I found that I get a much better service if I maintain a
constant flow of traffic accross the link. So, whenever I bring up
the connection, I ssh into an online machine and then just ping
localhost. This keeps a constant flow of TCP traffic accross my Vodafone
link, which in turn leads to a more responsive service.
I'll post my configuration files below in case you need them, but if
wvdial works for you, then great!
To use the following configuration, do:
pppd call vodafone
And to kill the connection, do:
# Vodafone DNS Servers
# Eircom DNS Servers - for when Vodafone's aren't performing
# nameserver 220.127.116.11
# nameserver 18.104.22.168
/dev/ttyUSB0 921600 crtscts
connect '/usr/sbin/chat -v -f /etc/ppp/chat/vodafone'
