You seem to not understand that google since pixel 3 all have esim... So this prove that its not about a reserved deal as pixel phone not having esim support at Telus cannot be put on apple head.
I guess that Apple is also blocking carrier from activating pixel 3 , 3 xl , 3a and 3a xl esim? They all support it and are obviously not Apple device..Care to elaborate why then Telus could not activate them by Esim? Think for a second..
