I am the owner of the Samsung Galaxy S21 + 5G. Under Settings>My Phone my phone's number is listen as "Unknown". When I click on "Edit" it would not allow me to add my number.
How long ago did you swop? The cause for the Unknown number is because the number is registered to the Note. Nothing that you can really do to fix this. Hopefully a future software update will rectify it.
If you no longer need the data on the Note and have it backed up and restored to you current device then you can reset the Note to remove all configuration and memory. Theoretically, that should change the unknown config on your current device when the Android servers update or refresh.
It might be a server side problem that you can't fix with settings. I have a dual sim device,the one old sim shows the number,the new one didnt,and just out of the blue last week it started showing up and no settings was changed
Hi, Blommie this error commonly occurs when you transfer the number you were using on your old phone over to your current phone.
Your Samsung phone reads the phone number originally assigned to the SIM card and if you are no longer using that number (such as when you've ported over your old number to use with the new SIM card) your phone will no longer know what number you are using. Your phone in this case will list your current number as 'unknown' rather than incorrectly present the number originally assigned to the SIM card.
This information cannot currently be amended due to how the Android operating system registers a number to the handset upon first use. The issue may be resolved in a future Android software update, but until then rest assured that it has no effect on your device's functionality.
