Reference

Before you can set up SMS Service, you will need to know the following information:

• which COM port your modem is using.

  you can determine this by examining the modem properties in your computers operating system.

• the PIN number of your modem (if set).
• your service providers messaging center number.

  this may be already set up in your modem or you can ask your service provider.

OR, if using a remote SMS gateway:

• URL of HTTP request containing, at the very least, the remote server hostname, authentication credentials, message payload format, optionally header information for binary and concatenated messages; please refer to the literature of your provider (usually found under developer/API resources).

Once you have this information you can proceed to set up SMS Service.
