# IP addresses:
# - accept peers idea of our local address and set address peer as 10.0.0.1
# (any address would do, since IPCP gives 0.0.0.0 to it)
# - if you use the 10. network at home or something and pppd rejects it,
# change the address to something else

# negotiation stalls, try restarting the phone. To try with other GPRS
# operator setting, change the PDP contex setting. The settings work with
# all Ericsson models, but Nokia 8310 does not suppor QoS parameters with
# AT commands, so just delete those lines and it'll work.

# Set PDP context CID=1, protocol=IP, APN=internet:

# Set CID=1 QoS requirements from the network, not supported by 8310:

# Set CID=1 minimum acceptable QoS parameters, not supported by 8310:
