Hello guys,

How do sms sending apps work? I know how to code normal ones but how do I give the user free sms and stuff.

Do I have to make a deal with the service provider? If so, how does one contact them?

Thanks.

Same way. Just integrate an API into your app,
but put to no restriction on the sending(e.g no signing
up) - you'll be giving them some of your sms credits
you bought from the service provider -  for free.

I don't understand yet. Can I set parameters on the users mobile phone that'll allow their credit to be avoided and the app's credit used instead when they're sending from the app? If not, I'm guessing I'll have to use a website as backend to send the messages. Either case, how do I contact the service providers for this?

Do mtn and co have any sms gateway API for this?

Is it better to go through third party sms gateway providers?

I thought you were talking about web sms.
Yes, the way to go is to use a website as backend to send the messages.

BTW, what do you mean by

I know how to code normal ones

?

I meant sending using the device by using 'sms://number/port' in j2me.

So What do you suggest regarding the gateway? Do I buy from third parties or providers. Note that the app is not strictly for bulk sms.

It can be pretty difficult(if possible) to buy directly from the
provider, you'll have to buy from a third party.
BTW, we are into web sms and 've got API's, if you
are interested in buying from us we can give you a test
account and API documentation.

Okay, thanks. How do I contact you?

Hmmm, seems like you need a Java phone app that sends web sms. Try this free download at www.greenspek.com/download
