I had brought this A21 model, two month ago & I want to know how to do video calling from this model.. can you tell me is it possible to make VIDEO CALL on this phone...

Guest Author: Amit Kumar18 Jun 2013

Video calling through SIM is not possible. Video call possible through internet by using Skype, Gtalk etc. It is a cheating to customers by Karbonn. Do not go for it, no video calling and worst battery back up.
