I have been using vodafone since the time I am using a mobile phone.i live in a joint family with 7 phones in the family all using vodafone postpaid services.
I have never ever encountered issues with vodafone and for any issue that ever came up, the problem was always resolved by the customer care at vodafone.
I have changed my vodafone plans almost every quarter and have never encountered a problem.
In the remotest restauarants too, my airtel and idea friends ask for a hotspot from me.
Its neqly launched vodafone app is too comfortabke to view the usage of data and the calls etc.
Thank you vodafone.
