It doesn’t offer enough to justify the price difference. I live in the UK and the market is dominated by post-pay monthly bundles. These bundles rarely include video call as standard hence the marginal cost is very high. In my view the network provider (www.three.co.uk in my case) should try and use it as a differentiator as opposed to a revenue opportunity. For example on most of their bundles they give us 300 minutes a month to other phones on the same network. If I were them I would make video minutes the same as voice minutes for this allowance. That way I try and get my friends to join the network. As it is I used it a couple of times when I got my phone to try it out, thought it was quite fun, and then saw how much it cost me (because it isn’t included in the bundles) and since then I have not bothered to use it.
