-
  Over HTTP (via SMS Proxy)
-
  Over SMPP (via SMSC)


Choose one of them:

1. Navigate to **Administration** > **System Config Man**.
2. Set the value of the **sms.channel** parameter and click **Save**.

**sms.channel**: This parameter defines the channel to be used. Available values are **HTTP** and **SMPP**. The default value is** HTTP**.
