I just got a Z-boost system cell phone reception amplifier that works great. Some areas have bad reception due to many reasons. I am in Victoria shadow of Triangle Mt. Tell people about these options or sell them yourselves. All the more reason that Rogers is not even an option.
As a tech support representative I do see cell boosters suggested as a last resort for customers living on the edge of the coverage areas from time to time. Koodo can't exactly guarantee that they'll work though.
However, I think Koodo doesn't actively sell or promote boosters because it's too easy to spin as, "Come to Koodo, and if you don't get the best service - then just give us more money and you will...Maybe."
