Okay tanya It's work I have one more simple question. I want to check the phone and its entity. How does this relationship work?
I try this, but it didn't work.

$checkDublicated = $this->getEntityManager()->getRepository('PhoneNumber')->entityPhoneNumber($entityType)->where([
     'name' => $phone
])->findOne();

[tanya]

$attributeName = 'phoneNumber' or 'phoneNumberData'
$entity->isAttributeChanged($attributeName)

I wrote a custom hook. If the same phone in the database, it gives an error. I am using the beforeSave function. If I do not change the phone, it still fails. Idont want this. If the phone area changes, it needs to be checked. Could you help me?
