I have created an app that is able to do the following,
1) Receive and Send from the same port.
2) Send through an application to another phone that doesnt.
Now what i want to achieve is that i want to be able to do the reverse of no. 2. Which is, a phone without the application sends an sms to the another phone which has the app, and the app is able to detect that incoming messages. I been trying to change the ports and everything.
One of the thred mentioned that this cannot be done. While another said that the default port for all phone is either default :5000 or :0.
Which of the above mentioned cases is true ?
