Rather than posters speculating, is there any published public literature stating what, if any differences there are between the main Telus brand and it's flanker brands like Public Mobile and Koodo?
For example, it's been demonstrated in some locations, all things being equal with the same device and model where a Telus subscriber has cellular service and the Koodo or Public Mobile subscriber does not.
I don't think it would be unreasonable if premium subscribers have full access to cellular towers including services like VoLTE and those who pay less have some network features and channels blocked or restricted in favor of Telus subscribers?
