Thanks David and Stuart. I couldn't make it work using David's method, but It worked using this ppp.conf: default: set log CHAT
tim: set device /dev/ttyU3 set login "\"!chat -f /etc/ppp/peers/tim.chat\"" set speed 460800 set phone "*99***1#" set authname "tim" set authkey "tim" set timeout 120 set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0 #add default HISADDR disable ipv6cp I think the problem was the authentication. I tried to add user tim, and configure pap-secrets and chat-secrets, but it continued not to work. Anyway, the problem is solved now, thank yoy guys.
