Now I develop one application in J2ME where I send one sms to GPRS modem and then one Java application works with this message and finally the result is one SMS answer to the mobile. My problem is very easy and commun problem but I don't find the solution. It is in the moment when the mobile try to receive the sms (I develop it with one listener and listens the port 5000), because it goes directly to indox of the mobile and the application doesn't catch the sms.
The SMS that GPRS sends is in PDU mode. Please if someone can do some example of sms in PDU mode where you put the specific port, or other method to do this, please tell me.
Thanks you for all.
