Short Message - SMSHTTP Protocol Issues

This section provides configuration and diagnostics information for the SMSHTTP short message protocol driver. Consider the following items:

• Service providers do not follow any protocol standards for SMS messages via their web form interfaces. The content is specific to each provider. The UNS_SMSHTTP library is designed to read provider data from UNSConnections.ini for flexibility. The provider data holds information like the web site URL, POST data string, maximum message length, and expected success and response codes. The major challenge is keeping this data up to date. Because service providers may update their web site with new content or move their interface to a different URL, the setting may need to be changed.
• This library has been tested with many service providers such as Cingular, T-Mobile, Sprint, and Verizon in the US, and O2 in the UK.

Troubleshooting

If there is an error trying to connect to a service provider and you are required to go through a proxy server, make sure the proxy server information and credentials (if required) are set properly. If you are behind a firewall and do not use a proxy server, the port number (usually 80) required by the service provider's website must be opened.
