Question

SMPP versus POP for SMS

I am charged with writing an application that will let a client communicate with their customers via cell phone. They want to be able to send a question out and let the user reply with a simple answer, such as "Do you want to: A. Jump in a Lake, B. Take a hike, or C. Go Fish", and the user can simply hit REPLY with A, B, or C.

In researching this, it looks like the SMS gateway part via Cold Fusion will be relatively simple (start with Ben Forta's Dec 2005 article in Cold Fusion Developer's Journal), but I got stuck when it came to communicating with the cell phones. It seems (and I may have this part wrong, so PLEASE correct me!) that in order to have cell phones talk to your SMS Event Gateway, you need to sign up with an SMPP provider or a cell phone carrier (although that would limit you more) and they will connect a cell number to your IP address (basically) and create the connection.

SMPP providers aren't cheap, from what I see. It looks like they run upwards of $1,000 and more for setup, and $200 to $500 or more for monthly charges.

So, why -- and I mean "technically speaking" here -- why would anyone use SMPP when you can send and receive text messages with cell phones via POP email?

Looking forward to your answers!

I don't know what your specific set up is, but I just did this:

<cfmail to="myphonenumber@vtext.com" from="kodemonki@my-domain.com" subject="test">hi</cfmail>

and I got the message on my phone, then I hit reply, entered a message, sent it and it went back to kodemonki@my-domain.com. This probably isn't what you want because you probably want it to go to a form somewhere? Perhaps you could use <cfmail replyto= and then have some kind of form address in there. Like 169.212.1.1/dir/myCfPage.cfm I have no idea if that would work, but maybe you haven't tried it yet. Anyway, something to look into.

yes, that's correct.

look harder there are fairly cheap ones.
