Don't ever try to get help from the Vodafone Customer care. I searched google to get the following working settings. I use vodafone internet as they provide 2GB limited internet access for 95 RS which is quite affordable.
1. Ensure that VMC is activated.
make sure that vmc is activated send a sms ACT VMC to 144
2. Configure the following settings..
This is where u find the settings in milestone:
Settings->Wireless & networks->Mobile networks->Access point names
Here are the settings:
Add new APN.
Homepage: Any ****.
Connection Name: Any ****
Access Point Name: www
User Name:Leave it.
Password: Leave it.
Port Number: 0
Leave rest of the settings as they are - in default state. n enjoy.
I guess no more calls to vodafone cc. -
