code:
models:

<?php
use Phalcon\Mvc\Model\Validator\Uniqueness;

class Contacts extends \Phalcon\Mvc\Model
{   
    public function validation()
    {
        $this->validate(new Uniqueness(array(
            'field' => array('account_id', 'phone'),
        )));

        return $this->validationHasFailed() != true;
    }

}

        $contact = Contacts::findFirst();
        if ($contact == FALSE) {
            $contact = new Contacts();
        }
        $contact->phone = '1001';

        if ($contact->update() == false) {
            foreach ($contact->getMessages() as $message) {
                echo $message;
            }
        }

display:

SQL Statement: UPDATE "contacts" SET "account_id" = ?, "phone" = ?, "fullname" = ?, "sex" = ?, "created" = ? WHERE "id" = ?

has no change fields should not to save.

Try creating separate Uniqueness validator for each unique I think it cannot handle a set of fields. There is another bulletproof way to solve it - unique index for these fields in the database :-)

[phalcon]

Set a custom message in the validator:

<?php
use Phalcon\Mvc\Model\Validator\Uniqueness;

class Contacts extends \Phalcon\Mvc\Model
{   
    public function validation()
    {
        $this->validate(new Uniqueness(array(
            'field' => array('account_id', 'phone'),
           'message' => 'Account_id and phone must be unique'
        )));

        return $this->validationHasFailed() != true;
    }

}
