Thanks for the info. Several people have responded that most providers have a 
free email service that allows sending a text. I’d love to be able to do this, 
but for this client it’s just not possible to always get the person’s cell 
phone provider. So we will have to use a pay service.

Of all the SMS web services out there twilio.com seems to be the most popular 
with 4D developers. I have a few say they can provide me with some code to do 
the http work with Twilio’s API. So I’ll probably go that route.

It was a bit unclear to me exactly what the cost is with Twilio. Their website 
lists many services available for sending and receiving SMS and even MMS. From 
what I could gather it costs about $1.00 a month for the pay-as-you-go option, 
and 1 cent for each SMS sent. 

It is not exactly 1 cent for every SMS because you pay Twilio $0.0075 for each 
SMS and they you pay another fee to the carrier of the person’s cell phone. 
AT&T is $0.0025 per SMS and Sprint is $0.005 per SMS. In any event the cost 
seems incredibly low. 

If someone knows the exact pricing scheme for Twilio, I’d love to hear it. I’m 
not sure I completely understand it. 

One other question is do you need a cell phone account to send SMS with Twilio? 
If so, I guess the company could get a cell phone for the business and just 
never use it. It would be just so you could send SMS via 4D.
