number changed when phone upgraded

[kc48]

I upgraded my phone from a S7 to a S21 and moved the old sim card to the new phone. But the phone number has changed on the new phone. How do I get my old number back?

@kc48   If you upgraded your number shouldn’t change,    You might want to call customer services about this.

Hi @kc48 

If you dial your existing number from another phone, what happens to the call?

I can call my old number, and when i call another phone from my new phone the number comes up correctly. i guess its just a problem with the info in the settings panel
