can i activate the sim cards 24h a day?
yes. All done automatically for you. A timestamp will be associated with your activation.
If your question is about the referral, note that it can take from 5 minutes to a few hours, sometimes 3 to 4 hours to complete the activation. Only then will the referral be timestamped.
If you encounter difficulties, which is rare, you might need to chat with a representative . That can add delays so don't wait up.
Make sure you follow all proper steps from https://fizz.ca/en/faq/activate
