Never use Vodafone. This fraudulent company is owing lot of tax to Indian Government. As there are incompetent and fraudulent people in Indian Government, they are keeping quiet.
When ever you have some good charging mostly above Rs.30 they activate some bloody feature of ringtone or SMS or some nonsensical thing to grab your hard earned money. If they cheat on one day a million people they earn a 10 million rupees just like that. So my advice to all Indians is to quit vodafone india services. Let them go back to their own hell.
Be Indian and Quit Vodafone.
Love my mother country.
