As I know that Nokia and some others phone (like iPhone) are able to sent and receive class 0 SMS , is it possible for android ? Do Android have the API?

What is flash SMS?

Flash SMS is an SMS which is displayed on the phone screen immediately upon arrival.

Unless you choose to save the flash message, it will disappear upon navigating away and will not be saved in your inbox.

If several flash messages are sent to one phone, only the latest message will be displayed, and all the previous ones will be overwritten.

Class 0: Indicates that this message is to be displayed on the MS immediately and a message delivery report is to be sent back to the SC. The message does not have to be saved in the MS or on the SIM card (unless selected to do so by the mobile user).

For rooted Android it is possible to bypass an API and send Class 0 SMS. There is a project on Git Hub called ZeroSMS:

ZeroSMS is a proof-of-concept demonstrating a way to send Class 0 SMS on android >=2.3.

Note: this only works on versions 2.2 -> 4.1.2, the sendRawPdu method was removed, so you will need to find a new way to do this.
