Sending and receiving sms in backend of iPhone

I am new to iPhone application development. In the application that I am developing for iPhone there is a module which sends the sms without knowing to the user to my sms server and gets the response and displays the result. Is there any w开发者_StackOverflow社区ay to send and receive sms message in app?

Thanks in advance.

You should use data instead of SMS.

SMS are not a way to send information between a client and a server, but Internet is. And by using data, you also get a much more reliable transfer protocol (SMS aren't).

You shouldn't send SMS without the agreement of your users, because it can become really costly. Imagine you have a user on vacation in another country, and think that your app is using wifi, while it is using SMS. This user will be really mad when he will get is cellphone bill.

So even if you can do it, I think you shouldn't. And if you really need to do this, be sure that it is really clear to the user that your app is going to send SMS from his phone (with the charge of a normal SMS).

This is not possible with the iPhone SDK as it stands. It's probably not possible with any mobile platform without the user knowing about it as it's an obvious security hole.

I am also working on GPS-based application and I can have the device stop sending SMS back to the user every time the user send an SMS command. I think as long as the SMS is sent, it should be fine.

If the user wants to see the status of the device, then I might have to establish communication between my server and the device via TCP/UDP and have the iPhone app "parse" the information and display the status. Perhaps the best way is to have the server respond to the iPhone app saying "The device received your SMS command" and display it on the app so that the user knows his/her SMS were sent.

But yes, if we could get the location via SMS, then I could send those coordinates to the Google Maps app in the iPhone itself and it would display it for you.

I am the author of an App on Android which does this, called ImHerePlus. Check it out and see if it helps.
