See the class SMSManager on Android API.

There is a sendTextMessage method that you can use:

Try some code like this:

uses
  Androidapi.Helpers,
  Androidapi.JNI.JavaTypes, 
  Androidapi.JNI.Telephony;

procedure TForm1.Button1Click(Sender: TObject);
var
  destAdress: JString;
  smsManager: JSmsManager;
begin
  smsManager := TJSmsManager.JavaClass.getDefault;
  destAdress := StringToJString('0034123456789');
  smsManager.sendTextMessage(destAdress, nil, StringToJString('The message content'), nil, nil);
end;

You must add permissions to the project configuration. See the "Send SMS":

Send SMS - Allows an application to send SMS messages.
