Free GPRS Settings for idea simcards

GPRS on Idea simcards is by default activated,
In order to use it over mobile phones, use following settings:

Primary ip : 10.4.42.15
Primary port : 9201
Secondary ip = blank
port = blank
user = blank
pass= blank
APN GPRS = imis
If other applications on your mobile such as Google Maps etc. stop working , you should try apn name as ” Internet “. It has worked for me.
