I have read about 5G SA being launched in both eastern and western Canada, but I have not been able to connect to it in either Milton or Hamilton (yet). Does anyone have any more detailed information about where exactly 5G SA has already been deployed?
It exists but Telus doesn't have a coverage map specifically spelling out where 5G SA is enabled at present. You may also need to have a fairly new SIM card to use SA. I have a 5G SIM in my phone and my phone says that SIM doesn't support SA.
