The spammer just called number based on the number sequence. Their system didn’t know your number was new or not. It was unlucky that your new number got one. I personally had 5,6 calls per week.

Anyway, I would recommend you avoid publicly posting your personal number. Keep your personal information private.

Koodo has enabled a feature called “call control” to ask callers to enter a number to avoid robocall. https://www.koodomobile.com/en/help/call-control You can try it out to see if it works for you.

Also keep in mind that just because it’s a new number to you, doesn’t mean that the number has never been used before.

When someone cancels their line, the number goes back into circulation after a couple months.
