Sending Automated SMS Messages

Question

First, we use .net & sql server.

I have a client that is interested in a system that will send SMS messages at scheduled times.

I have never done anything like this except for sending an sms through an email gateway, like [email protected]. But, I don't think that is an option for this as, our database will store the phone number and ignore the provider.

Thanks for any input on tackling this problem.

Answer 1

Easiest way is to use an SMS gateway who provide an API. Check out txtlocal

If you use a provider such as txtlocal you have 2 options - you can either build the scheduling into your system, or you could have a batch process which sends the sms info and the time that you want it to be sent using their API.

Answer 2

I've used Clickatell in the past.

They have a RESTfull API, which means sending as SMS is as easy as constructing a URL with the message and recipient's phone number.

It's not free, obviously, but it's pretty darn cheap.

Answer 3

Well, you either have to use an SMS gateway as you mention, or get a PCI/USB GSM modem like this one which allows you to send texts straight from the server.
