Really it's hit or miss.
But you should notice that the public mobile service will become fully functional within a few hours once the ticket has been submitted.
Once your Koodo prepaid service no longer works (presuming you still had some time left in the current cycle), then replace with the Public Mobile SIM card.
The reason porting from Koodo pre-paid to Public Mobile requires CSA assistance is that they share the same system.
This is because TELUS owns Koodo and Public Mobile and PM piggybacks on Koodo's pre-paid systems.
In effect, it's not the traditional 'port' which is occurring, rather just moving provider from Koodo to PM in their system.
@Shaikh1 Please remove your phone numbers from this public post. As @softech has posted contact support for porting from Koodo prepaid to PM. For some reason there's something special that requires CS Agent to intervene in this port. Contact them here,
@Shaikh1 for porting from Koodo Prepsid, since you have activated already, please submit ticket with support and ask them to help porting
