Telus reported 9.128 million mobility subscribers in Q3 2021. And reported that "approximately half" of these (so approximately 4.564 million) were Telus Mobility subscribers.
Koodo Mobile had a serious data breach in 2020 which could have affected "3 million" and "nearly 75%" of their subscribers. Which suggests they had around 4 million subscribers at that time.
The remainder would have to be Public Mobile subscribers. Roughly 564,000 total. Give or take a lot, maybe.
These data span several years in an ever-changing market which has seen one or two covid recessions, closed borders, a surprising amount of impressive (and expensive) new phone tech, the giant smartphone brands (Apple and Samsung) reporting lower sales than previous years, and the Rogers rollout of 5G. So they're only loose estimates.
Although I suspect that more and more people have been downsizing costs on their luxuries and lifestyles (which always starts with finding a cheaper phone bill first) so maybe third-tier operators like Public Mobile have seen a surge in subscribers - especially compared vs the ripoff prices offered by Telus Mobility and the other first-tiers. Public Mobile certainly seems to get a lot of response every time they run another one of their endless stream of "for new customers only" promos, even the bad ones get pages of questions and comments and support requests.
