Okay so I recently got interested in the whole VoLTE thing with my iPhone 6. I'm new to this so take it easy on me. I was curious as to how it works, I understand that it uses LTE to enhance call quality. But does it use up data and if so is it a significant amount of data? Another question is would you be able to talk on VoLTE and say send and email or browse the web, like on GSM networks?
