You cannot register WhatsApp on a new phone without a code. But you can link a second phone as a companion device, which needs a QR code, not a text.
Registering on a new phone always needs the 6-digit code sent to your number, plus your two-step PIN if you set one. If you no longer have the number, you cannot register that account on a new phone.
Linked devices keep working while your main phone is off for a while, but your main phone must check in regularly, or the links log out.
Before switching phones, read moving to a new phone.
WhatsApp on a computer or tablet is always a linked device: you scan a QR code from your main phone, and no new code is sent. This is the right way to use WhatsApp on extra screens without moving your main account away from your phone.
Not as your main phone. You can link it as a companion device using a QR code.
You need to receive the code on that number, so ask your carrier for a replacement SIM.
Not if you back up and restore on the same number.
