I have had a really bad experience with reliance. I switched to reliance from TATA DOCOMO as I recieved a call from reliance saying I will get unlimited local and STD for only 599.(Jalsa 599) which was a wrong information.
They kept calling me until I switched to reliance.
Once I switched I got huge amount as my first bill and later upon enquiry I realized that I had only 4000 minutes free.
On contacting the reliance team they talked to me in a very cheap manner and never attended my calls later.
Please dont fall into the trap of reliance!
