My old sim has been deactivated and most of my contacts know me by my old number. I want some way to register my whatsapp to that old number

  • You have to have active SIM card for the first-time registration/authentication (either by using SMS, or voice call). Other than that, I don't know if it's even possible to "cheat" WhatsApp server.

Phone numbers aren't tied so much to the SIM card, but to the provider via your SIM card. Your old phone number can be reassigned to another person now, so it would be unwise at best, probably illegal, to make Whatsapp use your old phone number.

In short, "your" old phone number is no longer yours.
