My apn is wap.gocbw.com and the username is cbw, no password
I can send and receive sms messages but I cannot get the web server to work. I am using the arduino gsm shield with the gsm library. I will provide any information and do any testing you ask to get this problem solved.
Thanks!
BTW I tried to ping once the serial monitor gave the ip address, and it timed out every time. NO response.
I also have another gsm shield with a SIM900 but cannot find any webserver examples anywhere. I am able to send sms messages with that one also.

So what makes you think you can run a web server on a GSM system? What is the IP address of your web server on the GSM system?
The fact that there is a GsmWebServer example code in the GSM library makes me think that I can have a webserver on my arduino by using the GSM shield. The IP address is apparently generated when the arduino runs the code and can be seen by using the serial monitor. It takes a minute to do its thing and then it displays the IP address of the server. I then ping that IP address and get no results. This is by using the arduino GSM shield straight from their store. I also have the other shield but I don't know how to get that working. I can't find any sample code for that.
Thanks for the reply. Sorry, I didn't understand what you were asking. NO, the IP address is certainly not in that range. Give me one minute and I will update with the IP address it generates.
Update: Okay, here is exactly what the serial monitor displays, the server is still running:
Connected to GPRS network
Server IP address=
10.69.162.129
BTW I am using an arduino UNO just in case that becomes relevant at some point.

The 10.69.162.129 appears to be a private LAN IP address of your mobile service provider. Doubtful if you will be able to connect to it from the outside world.

A number of network operators do not allow for incoming connections from the public internet, but will allow them from inside their own. Check with your operator to see what restrictions there are on data use.
How can I find a msp that will allow me to have a webserver accessible from the public internet?
I have a problem with set up a webserver. Server attached to GSM network and ping is OK, but I dont know how to configure a server to replay "Hello" or return to client a analoge value. I have no idea any more.
The library in Arduino 1.0.5 for GSM shield (Telefonica -GSMwebServer) is very simple because include command clientprint () similar as Ethernet shield clientprint().
I offer a small prize (paypal) those that solve this problem:
clientprint (value of analog pin) - 1.0.5 with Telefonica Arduino GSM shield === similar to this with SIMCOS SIM900 library ????
I spend hours and hours and I'm stuck in this problem.

I am offering payments (via paypal) to those that we solve the problem/solution WEB server (UNO+GPRS SIM900) where client connect to WEB server and read a value of analog pin (A0-A5).
Please I need a solution anyone know how to do it?

I correct a basic code (server SIM900) and now working better but still not as I like. Client connect to the server but problem is how to regular disconect from sending mode (AT+CIPSEND), becouse Ctrl+Z (1a0x) not accept. And server non stop sending "MHE TEST", look code bellow.
