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.

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.

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
