Welcome to Android Central! I may be wrong, but I thought video calls require the phone to be from the carrier itself, not unlocked, since video calling is a function of the carrier's VoLTE network. You're not talking about Skype or Hangouts, right?
Yes i am talking about the Carrier Video Calls, nope not skype or any other app, i bought the phone unlocked and i am using it in a different country, but i cannot find the option to make a Video Call in the first place !
Should i be giving Orange(carrier) a call? Or does the mobile itself doesnt support native Video Calls ?
I confirmed with one of my colleagues -- native video calling from your carrier requires the phone be from the carrier. You could give Orange a call, but I don't think you'll be able to get it on that phone.
