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.
