How to send SMS programmatically using UDID without cost in iPhone

I want to know is it possible to send SMS programmatically using Objective-C in iPhone using UDID means that the TO address should be an UDID of the other iPhone tha开发者_JS百科n phone number.

You cannot send an SMS to another phone that you only know by UDID. An SMS always needs a phone number as address.

If you know the UDID then you can send Push Notification using your own server.

THIS WILL ALLOW THE USER TO CHAT WITHIN YOUR APPLICATION.

No, this is not possible.

First SMS works with phone numbers, zo not a UDID.

The User will also be charged for sending a SMS and you can only send a SMS via de MFMessageComposeViewController. There is not way to do it in code only.
