Hello everyone. 
I am trying to implement sms verification on Captive Portal in XMC/ExtremeControl. 
Based on user-guide, I need to add service provider in the list. Simply adding the service provider in the list will definitely not work as far as my understanding. I have purchased subscription from one SMS Gateway  service provider. How/where can I add this account in XMC? 
Will you please help me making this work? 🙂
