When you get a 9038 error on iOS at the end of the reactivation of your itsme® account, it means your itsme® app is not up to date after a smartphone change.
To solve this please remove the current version of the itsme® app and install a new version of the app. Reactivate the itsme® account again and you won't get this error anymore.
! Always reactivate your account via the itsme® app or from the website www.itsme.be; never follow a link in an email or text message.
