We are a stone's throw from downtown Edmonton and have almost no signal. One bar most of the time sometimes two. It's gotten significantly worse in the past few years, now if I walk from one room to another my calls will drop. Literally have to stand in one spot to make a call - and yes, wifi call assist is on. All three Telus phones (two personal, one work phone) all have this problem. Anyone else barely able to make a call from the Brickyard in Riverdale, Edmonton?
You can report signal issues to telus here. If you have W-fi calling enabled you should not have issues receiving/placing calls or sending texts etc, sounds like it's falling back to cellular if you have issues.
