I think you missed my point B 
With telus, you dont need to ask them to transfer your account. If I said that to them, they would just tell me to put my sim card in the new phone and it would work.
I know because I have a telus phone and I’ve done it lots of times
thats some messed up shit, for all i know telus has always been cdma, maybe they just brought this sim card application out…
telus used sim cards before.
PEOPLE
SIM CARDS HAVE NO DIRECT RELATION TO GSM,
it just happned that gsm companys use then first and had more support for the technology,
