So volte+wifi calling is likely to be the future of wireless carrier, but I just can't understand what's the point of this technology besides the improved calling quality. What other benefits can it bring to us, as a daily consumer who is paying more than $50/mon. to the greedy carriers. So here are my questions: 1. All calls via volte or wifi are counting against our airtime minutes, so what's the point of using volte besides occasional international roaming calls (wifi is still needed at this point to make international calls abroad to save roaming charge) and better connection in area where the signal is subpar. 2. Volte calls are currently implemented internally, i.e among users who are using the service from one carrier, users between verizon & at&t are not able to call each other on volte, as different carriers use different codec. Even if the transcode is completed among wireless carriers, will it be implemented between wireless carriers & traditional landlines? Forgive my ignorance if i'm wrong, but I just don't see such a fervour on this technology, could it just be a fancy gimmick more than a revolutionary tech that could benefit our day-to-day life?
