I use Ozeki ng to send sms through database user.
The problem: After sending the sms, its status will not be "delivered".
It remains "sent" despite the delivery reports arrive through the service provider connection.
I followed their setup guide (http://ozekisms.com/index.php?owpn=164
) carefully, I installed the database user again and again, but the problem is still alive.
Please, help me!!!!
