I have developed an application in which I have used SIM808 module for cellular communication (GPRS). I am facing a problem that I am unable to test the TCP/IP Socket and HTTP Connection as the server application is not yet complete. As far I understand I would require some testing mechanism that would be hosted on Internet (Online). Kindly advice how should I test the TCP/IP Socket and HTTP Connection. Are their and tools available like Hercules (TCP) or Postman (HTTP) that are hosted on Internet?
