Orginal SIM phone number showing in settings

[SurreyEagle]

Hi, I have an Android Google Pixel 6a. I successfully ported my old number from my previous provider and whatsapp, texts, calls etc are all displaying correctly.

But when I go to Settings --> About Phone --> Phone number the original SIM number is still showing. 

How can I get my phone to recognise and display the correct number in settings?

Thanks

@SurreyEagle Is there no option to amend it manually? Can you try a Network Reset?

Okay @SurreyEagle, have you logged-in to your Google Account and checked the mobile numbers for the devices registered in your Google Account? 

Maybe checking and updating the information in your Google Account, as necessary, will fix this issue.
