Hello,

We are looking to replace all Twilio messaging being currently handled by the "system.twilio.sendSms" function. Is there a documentation available that will help us learn how to use the Airlink RV55 for SMS messaging with scripting?

It is important to us to retain how the current SMS messaging works due to the time already spent on custom coding/projects.

Thank you!

The Airlink module doesn't provide scripting functions for sending custom SMS.

I can't help but think you're making a mistake moving from Twilio to Airlink. Most people who change do it in the other direction. What's prompting this change?

Thank you for your reply!

The change is due to the higher-ups wanting to simplify things on the IT front.  
I can inform them that they may be doing the exact opposite.
