I assumed that a flagship phone like the Google Pixel would allow for simultaneous voice/data. That means that if I'm talking to someone on the phone, and let say I need to reply to a text at the same time or look on Google Maps for directions to a place, I shouldn't have to hang up to do that first. So I've checked every setting on my phone and made sure HD voice is activate on my line, but I still can't talk on the phone and use data at the same time. Am I missing something here?
