Why is my internet limited to 3g when on a phone call?

I am using an iPhone X. Every time I am on a phone call my mobile data speed is limited to 3g for some reason. as soon as I hang up it switches back to LTE. Does anyone have any insight as to why this happens? Is it a problem with my phone or with the Fizz service?
