can't send otp via sms

[JSC NKBank]

Dear support .Pls help

Any custom1.php fix does not work in transmission.

Perhaps there is a problem with the absence of + in the number code?

*******

function smshub_custom1 ($msg, $mobile, $flash, $sender, $username, $password, $account, $url, $proxy, &$error) {

    // load WSDL file for Custom1 SOAP SMSC

    $wsdl = "smshub.wsdl";

    if (!file_exists($wsdl)) {

$error = "WSDL file '$wsdl' does not exists";

return false;

    }

    

    // set HTTP proxy connection

    $options = array('exceptions' => false);

    if ($url != NULL) $options['location'] = $url;

    if ($proxy) {

$options['proxy_host'] = $proxy['host'];

$options['proxy_port'] = $proxy['port'];

if ($proxy['user']) $options['proxy_login'] = $proxy['user'];

if ($proxy['password']) $options['proxy_password'] = $proxy['password'];

    }

    

    // create SOAP client

    $client = new SoapClient($wsdl, $options);

    if (!$client) {

$error = "Could not load WSDL file '$wsdl'";

return false;

    }

    

    // set soap request

    $req = array("mobile"=>$mobile, "text"=>$msg,"username"=>$username,"password"=>$password, "sender"=>"NK_Bank", "flash"=>$flash);

    

    // send soap request

    $ret = $client->__soapcall("sendmsg", $req);

    

    if (!$ret) {

$error = "Invalid SOAP response";

return false;

    }

    if (is_soap_fault($ret)) {

$error = $ret->faultstring;

return false;

    }

    

    // Check soap response and return 

    // -> true on success
