@dust2dust I don't recommend buying direct from Public Mobile, especially if their current sim is damaged and they need to get up and running quickly. It can take weeks to be delivered.
Amazon for $4.99 is a great deal:
Public Mobile Prepaid SIM Prepaid Phone - (Universal/SmartPhones), Packaging May Vary https://a.co/d/0TySTlK
Or find a local retailer: https://www.publicmobile.ca/en/on/pick-up-SIM
