Twilio – continue messaging after reaching an unsubscribed number

I want to send an sms to a list of numbers. One of those numbers may have unsubscribed. However at the moment Twilio throws a very ugly error message if it encounters an unsubscribed number and then just stops.

How do I make it continue going through the array of numbers to text?

Here’s my code so far:

foreach($phoneNumbers as $phoneNumber) {
  try{
    $client->messages->create(
        $phoneNumber,
        array(
            'from' => $twilio_number,
            'body' => 'Testing from my website'
        )
    );
  } catch (DeserializeException $e) { }
    catch (TwilioException $e) { }
}
