When using wvdial for connecting to Internet through a Airtel gprs, with a gprs enabled mobile, if the wvdial program continuously tries connecting and fails …. Add the following line in the /etc/wvdial.conf file

Init3 = AT+CGDCONT=1,””,”airtelgprs.com”

where airtelgprs.com is the accesspoint of Airtel

Hence the etc/wvidal.conf will look like

[Dialer Defaults]
Init3 = AT+CGDCONT=1,””,”airtelgprs.com”
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
ISDN = 0
New PPPD = yes
Phone = *99***1#
Modem = /dev/ttyACM0
