I am looking to add SMS functionality to the real estate site i am planning. Does anyone know if any of the local mobile operators has a free to use API ?

There's a one i've used - and it worked. But you need to register an account with them, which they'll use to credit every sms transaction.

I tried it so a an sms app i was developing at one time and it went well. Be warned though, the site's design might discourage you.

Web2SMS Pro Developer API:

Hope this works

Yes I remember that one. It does look like knocked together by a schoolkid just diiscovered dreamweaver . Their system won't work for me i think

too bad. but if you do find a solution do please contribute to the thread. Or you could ask cmon. he was working on the same. Not sure what came out of it.

Im tempted to recommend clickatell (http://clickatell.com) for a couple of reasons:
1. They have the best api connection Iv ever come across.
2. Their service is good and realiable
But then here are the issues with them
1. You may find it hard to make online payments with them. As a Nigerian, u can only use direct bank transfer
2. Except u can find a work around (talking to them or watever), at last check, u cant send using any 'sender id' u want. Sender id is the name or number the sms sender is set at. U have to register any sender id u want to use. This is actually due to scam purposes.
3. Their fees is somewat costly except u will b buying quite a quantity.
So, to make things simple, I will say u check out http://smslive247.com - easy payment and api integration.

Truely, I was working on an SMS system. I found out that most bulk SMS service in Nigeria are expensive so I'll now be using a service provider in India (www.routesms.com). You'ld have to do the bank transfer stuff. I really don't mind cos it's more cost effective.

why dont you try utiware.net

Realy
we are working on an SMS system. I found out that most bulk SMS service in Nigeria are using a service provider in India (www.mnatives.com) You'd have to do.
