You can't change it on a SAMSUNG phone but you can on an Oppo.

My advice comes from being a UK Samsung phone user.

Current Devices:
  • Samsung S21 Ultra 5G 256Gb > Model: SM-G998B/DS.
  • Samsung Galaxy Watch4 Classic > Model: SM-R890NZSAEUA.
  • Samsung Galaxy Buds+ > Model: SM-R175.

The phone number is actually stored on the SIM. When I wanted to add my number I had to put the Sim in a friend's IPhone. I could then edit the number. Putting it back in my Samsung it read the number OK.

@danjoy42: SIM cards contain a temporary placeholder number before your own number is added by your mobile network provider. On occasion, this can cause a read error in Settings > About Phone, causing it to show as 'Unknown' or, in your case, to show the default number. Typically this doesn't affect your network capabilities in any way, however you may wish to contact your network to request a SIM swap to see if this resolves the issue.
