I've had the same issue... But when I paid with another card it worked. I did notice however that it automatically changed my province to something other than mine and had to switch that back. Please let us know is it was ever resolved.
If your daughter is activating a new SIM card with Public Mobile, she can easily port in the number in the electronic form. I believe it was the 2nd step of the process. You will have to enter your phone number and the system will check whether it is...
