Unsolicited calls after SIM swap at Vodashop

[francs]

I got a second sim and number with my Vodacom contract 14 months ago, but I never used the 2nd SIM and subsequently lost it.
Last month I decided to get a replacement sim from the Vodashop and put it in an old phone I had available.
As soon as I turned it on the spam calls started. A few a day.
So how did the marketing companies get my number?

This is a serious concern for me, because what other information are sold to third parties?
Think of all the confidential paperwork the cell companies require to open a new account.
Certainly information that can be abused.

Or am I just paranoid and the marketing companies were lucky when they dialed a previously unused number?

Probably a recycled number.

Previously USED by somebody else - in other words it's a recycled number.

I signed up with https://www.nationaloptout.org and get much less marketing calls.

It might have been used before, but it's the same number I got 14 months ago.
Surely they'll stop calling a number if it's unavailable after a number of months.

Nope, they keep calling.

That ethow link reads like a spammer who is having a rough time with truecaller. It’s quite clear that the information is publicly sourced. I reported spam numbers when I used the app.
