Set up your mobile network connection

The next step is to connect your system to the mobile network. To do this there are two options. You can connect to the mobile network like any other mobile phone does, in this case you need to connect a GSM modem or you need to connect through an Android mobile phone. The other option is to connect to the Short Message Service Center (SMSC) of a mobile network operator over the Internet.

Send test SMS message from Ozeki 10 SMS gateway

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 Test tab, 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.

How to send a test SMPP message:
  1. Navigate to the SMPP connection's details page
  2. Select the Test tab
  3. Enter the recipient phone number
  4. Make sure the phone number is in international format
  5. Enter the message text
  6. Make sure the message text is less than 160 characters
  7. Click on the Send button
  8. Check the SMPP logs

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.
