a lot of us don't get very great service in some parts of our homes. i get around 3 bars of 3g and 2 bars of lte when inside. however in my basement like most people i have one bar only, but i do get a great wifi signal. it would be great if Koodo offered wifi calling just like bell, rogers, virgin and fido have. fido and virgin have the same priced plans as Koodo which is making me want to switch, but i don't want to because i love Koodo.
Google hang out dialer, It's free and it's part of Google hang outs, if you have a android phone this is your answer. I use this when I'm calling the US (free) or when I'm in the US and I need to make a phone call (Free), It is WiFi based it also has really good voice quality.
