By adding stream plus you will be activating the 4 services via Koodo self serve.  Anyone who you setup with profiles or logins to the services will get access.  It doesnt matter if the users are on your koodo account or not

So, from what I read, Telus/Koodo didn’t consider how many people in the same Koodo account. Instead,  they would link individual service with your Koodo. And only 1 account from each service is linked with Koodo.

So there are one netflix account, one apple+ and one  discovery+ for each streamplus subcription. Each provider however allows 4 (or 6) devices to stream at a time.
