If you can’t receive or make calls. Check to see if your old Koodo SIM is working.
If it is, did you reply to the text confirming you are porting over to PM with YES within the 90 minute time frame?
The best thing to do is to contact a CS_Agent to look into the problem.
As from earlier, please be aware that being unable to make outgoing calls using the Public Mobile service is unrelated to number porting.
It shouldn't take more than couple of hours to migrate. Did you try to reboot your phone and take out/insert back the SIM?
As outgoing calls aren't working, the issue would be related to something other than number porting. Service aspects such as outgoing calls (but not incoming) should work immediately.
