Hi Uday, hi you try to change this line in the example (as well as in the library code lines 133-34 of the VodafoneUSBModem file):

example

int ret = modem.connect("pp.vodafone.co.uk");

library

strcpy(network, "Vodafone UK");
strcpy(apn, "pp.vodafone.co.uk");

for this (that correspond to pp india):

example

int ret = modem.connect("pp.vodafone.co.in");

library

 strcpy(network, "Vodafone In");
 strcpy(apn, "pp.vodafone.co.in");

I hope this will help you

Greetings
