Patterns in content message

An example should be like this

add_filter('wp_sms_single_dispatch_arguments', function ($arguments) {
    // Retrieve the subscriber by mobile number
    $subscriber = \WP_SMS\Newsletter::getSubscriberByMobile($arguments['to']);
    // Retrieve the user by phone number
    $user = \WP_SMS\Helper::getUserByPhoneNumber($arguments['to']);

    // If the subscriber exists, replace {display_name} with the subscriber's name
    if ($subscriber) {
        $arguments['msg'] = str_replace('{display_name}', $subscriber->name, $arguments['msg']);
    }
    // If the user exists, replace {display_name} with the user's display name
    elseif ($user) {
        $arguments['msg'] = str_replace('{display_name}', $user->display_name, $arguments['msg']);
    }

    // Return the modified arguments
    return $arguments;
});

Please consider the Delivery Method in the settings should be set on “Batch SMS Queue“

Best
