This topic explains how to configure AirVantage to send SMS with HSL.
You can start creating a trial account for a ’30 days trial for business’, by following this link: http://www.hslsms.com/demo-request
HSL trial accounts are only available for business users. You can contact their Sales department here: http://www.hslsms.com/contact/
Before you purchase some credits and start configuring this account in AirVantage we recommend you use the trial credits provided, to verify that you can reach your SIM cards from the HSL gateway.
