@qswupublic No, PM is a prepaid provider and do not provide prorated refund. So, you should time your port out time better. But do not wait till last day as porting process can have hiccup , from PM or from your new provider
Usually, it is best and safest to port around the 25th days , it gives both carriers enough time and minimize your loss
One thing, if you are porting into Koodo or Telus, call their agent and them them you came from PM , they might be able to do something to offset the money you lost
