How to send SMS Messages

The Symfony\Component\Notifier\TexterInterface class allows you to send SMS messages:

// src/Controller/SecurityController.php
namespace App\Controller;

use Symfony\Component\Notifier\Message\SmsMessage;
use Symfony\Component\Notifier\TexterInterface;
use Symfony\Component\Routing\Annotation\Route;

class SecurityController
{
    /**
     * @Route("/login/success")
     */
    public function loginSuccess(TexterInterface $texter)
    {
        $sms = new SmsMessage(
            // the phone number to send the SMS message to
            '+1411111111',
            // the message
            'A new login was detected!'
        );

        $sentMessage = $texter->send($sms);

        // ...
    }
}

The send() method returns a variable of type Symfony\Component\Notifier\Message\SentMessage which provides information such as the message ID and the original message contents.
