Do you support SmsGatewayCenter SMS API Module?
CiviCRM is open source software, so there's no "you" to address this to.  Anyone is free to make a plugin to interface CiviCRM with this provider.

As of right now, no one has - but SMS provider plugins are relatively simple, and if you (or someone you sponsored) was able to put in a few hours, you could likely make this happen!
