Wired function invocation

When is the wired function in this component called?

import { LightningElement, api, wire } from 'lwc';
import { getRecord } from 'lightning/uiRecordApi';

export default class ContactViewer extends LightningElement {
    @api recordId;

    @wire(getRecord, { recordId: '$recordId', fields: ['Contact.Name'] })
    wiredContact({ error, data }) {
        if (data) { /* ... */ }
    }
}
