phone switches from LTE to 3G as soon as calling someone and stays on 3G, why?

My phone (iphone2s) switches from LTE to 3G as soon as I start calling someone and stays on 3G. The only i have figured is to go to setting -> cellular -> cellular data option ->Voice and Data and then switch from LTE to 3G and then from 3G to LTE again. This is weird.

It doesn't look like VoLTE is available on Fizz. Have you waited a few minutes for it to reconnect to LTE after the call? On my phone, I see it flip to 3G and then go back to LTE a little while after the call.

Yep no VoLTE on Fizz, not yet!!
Does exactly the same on my iPhone6.
Goes right back to LTE after calls!
Flawless anyways.
