It is important to mention that the OZX hostname and port plus the username and password are provided by your SMS service provider. For example if you contact Vodafone, and ask for an OZX SMS service, you will sign a contract with them, and often an attachment of this contract will contain the connection following information. If you subscribe to an SMS service on-line, you will likely find this information in the on-line control panel of your SMS service provider. Of course you can always ask your SMS service provider in e-mail and ask what are the OZX server connection details.

Check the OZX log

Once the OZX connection is configured, you should check the OZX connection log to see if the system connected properly to your SMS service provider. If the system connected properly you will see the "Connection online" log entry. The SMS connection logs can be found in the following directory in Windows: C:\Program Files\Ozeki\Data\Logs\Connections\. In this Event tab of the OZX connection's details page, you can see a preview of the log. This page contains the last 100 log entries. Note that the OZX log files are rotated to save disk space.

Send a test SMS message

Once your connection is connected, you can check to see if it is ready to deliver SMS messages by sending a test SMS. To send a test SMS message, you need to open the Admin user, and you need to enter the phone number and message text. It is recommended to provide the phone number in international format. This means the phone number should start with a plus sign followed by a country code. If your local phone number starts with a 0, it is likely that you will need to drop the 0 prefix. For example if your UK phone number 07958663698, you would send the test SMS to +447958663698.

You might ask why should the message text be less than 160 characters. This is because GSM system was designed to send 160 character long text messages. If a message is longer, it will be split into multiple message segments, and will be delivered in more than one SMS message.

After the message is successfully sent, you should check the OZX logs. The OZX logs will reveal the low level OZX messages, that are used to pass the message content to the SMS service provider. These messages are also called an OZX PDU (OZX protocol data unit). If there is a problem with message submission, your SMS service provider will ask for the OZX logs. In this case, you need to send the OZX PDUs to them. For every SMS submission, two OZX PDUs will appear in the log.
