Using SIM Cards without fixed IP | Telit Cinterion IoT Developer Community

June 14, 2015 - 9:04pm, 3391 views

I am trying to create a small HTTP Server on the EHS6T. SIM cards with fixed IP are expensive, so need to prove the application with a standard data SIM card before I use a fixed IP SIM.

The HTTP Server is required to respond to a users request from a standard browser window.

I am using java sockets classes for the internet connection which uses the GPRS settings for the ISP I am using. I am using ServerSocketConnection class which is also being used to retrieve the SIM IP address. I am assuming this is the current IP address that has been allocated by the SIM card provider ??. However if I try and ping this IP address or access via a browser window I just get a timeout error message.

Am I doing anything wrong above with my method for 'proof of concept'. Why am I unable to access the Server on the EHS6T.

Any clues on how to fault find the above would be appreciated.
