Hi Codee, 

I believe WhatsApp has a WhatsApp Business API, but they charge for that as well, unfortunately.

Hi Dave, I get it. Thanks.  What about utilizing Google Voice for sms? 

For any of these services, you can search to see if they have an API, and if they do, we can most likely use it.

The issue with SMS messages, though, is that the carriers themselves charge a fee, so there are typically not any free providers.  And if they offer a free trial, it's just to get you using their service or a loss leader to sell other services.

For low-volume SMS, any of the providers work because it won't cost much.  For very high-volume SMS, what some people do is route it through an actual cell phone.  Last time I checked there was Android apps available that would essentially act as a "server" that runs on a cell phone and proxies SMS messages.  That way if you have unlimited texts on your phone plan you won't pay extra.

Yeah, the cost there is likely just the setup of the code; the per-message fees should be pretty minimal.
