This phone number cannot be used for verification

[Elarabi]

When I try to put my phone number, I get an error "This phone number cannot be used for verification."When I try to put a different phone number, I get an error "This phone number cannot be used for verification." 

any help ?

I also encountered the same problem. After testing, I can only fill in the number that has been filled in on this page before, otherwise it will prompt that the phone number cannot be verified. I don't know if this is a bug, otherwise there should be no reminder.
