Telegram Privacy Query

I’ve got telegram on my phone. I set it up using a brand new simcard, let’s call that Number B. After setting it up I changed back to my normal simcard which I’ll call Number A. I can see my contacts from Number A on telegram. Can my contacts see that I’m on telegram and if so with which phone number?

Really appreciate any support or ideas on where to crosspost. <3
