Sample wvdial configuration file

• Stored in ~/.wvdialrc
• Change “dst.internet” to your provider’s APN

[Dialer dstbt]

Modem = /dev/rfcomm0 # modem device
Baud = 115200 # 921600 / 460800 / 115200 / 57600

Init = ATZ # far card with no PIN
# Init = ATZ+CPIN=”0000″ # for card with PIN, replace 0000 with your PIN

# If you know your ISP’s APN, specify it instead of YOUR_ISP_APN below.
# There’s also an APN table at https://wiki.ubuntu.com/NetworkManager/Hardware/3G .
# use one of the following 3 options. change to your providers APN
Init2 = AT+CGDCONT=,,”dst.internet”
#Init2 = AT+CGDCONT=1,”IP”,”YOUR_ISP_APN”
#Init2 = AT+CGDCONT=1,”IP”

# Most services/devices dial with *99# . A few seem to require *99***1#
Phone = *99#

# These often suffice, but your ISP might require different details. They’re
# often dummy details used for all users on the ISP, frequently the ISP’s
# name, but some ISP’s do require you to use a real username and password.
# any details possible
Username = internet
Password = internet

PS: bmobile customers change APN to “bmobilewap”
