Check to see if your Public Mobile services still work.
I remember that even after porting out from a Telus based company in the past (Koodo), the service does terminate immediately upon porting out, but the sim card does still connect the network and will appear to have a usable signal/connection. However, if you tried to place a call, you would receive a pre-recorded error message. That went on the remainder of the billing cycle even the the account had already been closed out. It's possible that the Public Mobile sim could be doing something similar.
But yes, any port out is suppsoed to cancel the old provider's service automatically.
