Just in case - I have 2 phones - Samsung which is currently in service and LG that is no longer in service. I used LG Android 10 before I upgraded to Samnsung S23 with Android 13.

Both of them show the same phone number even though LG is no longer in service with the cellphone provider. So it's not unique.

Steps to get device's phone number:
Step 1: Grant runtime permission

Manefest:

'''''''''''''''''''''''''
''get device phone number
AddPermission(android.permission.READ_PHONE_NUMBERS)
'''''''''''''''''''''''''

Step 2: run the code below

B4X:

'This event will be called once, before the page becomes visible.
Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    '1 get device phone number, if any
    rp.CheckAndRequest("android.permission.READ_PHONE_NUMBERS")
    Wait For B4XPage_PermissionResult (Permission As String, blnResult As Boolean)
    If blnResult=False Then
        ToastMessageShow($"You need to grant Phone permission for the app to function correctly"$, True)
        Return
    End If
    
    Try
        Dim pi As PhoneId
        Dim cell As String=pi.GetLine1Number
        LogColor("phone #=" & cell, Colors.Blue)
        If cell.Length>0 Then
            ToastMessageShow("phone #=" & cell, True)
        Else
            ToastMessageShow("Unable to get phone #", True)
        End If     
    Catch
        Log(LastException)
    End Try
End Sub

As written in https://www.b4x.com/android/forum/threads/sdk33-how-to-get-unique-number-of-phone.146991/post-931661
it is not possible to get the Phonenumber in Android 10+.
Even if there are some example they may not work. You just find out for yourself.

Ask the user for their phonenumber.
Send the number to your server.
Send a SMS with a Authentificationcode to the number from your server.
Let the user enter the code to verify it.

It works for me on my Google Pixel 4A, Android 13. It's time that you test it on other phones.

hi & thanks for your input
i got this but these friends said their sample works on latest android & SDK so i hopped...
using the ask for phone & verify by sms is a known "trick" but not really suitable for my needs
so i'll have to think of alternatives unless someone will come with a working solution / work arround
