I think I have some trouble on understanding the GSMClient connect(server,port) function.
The connection is successful (sometimes, but the aleatory of connection is another problem), with for example the server "arduino.cc" or "google.com":
... GSMClient client; ... client.connect("arduino.cc", 80) ...
but it is always unable to connect to some my sites for example "www.ongburkina.org".
What should I ask to my provider?
The site is not a server? The port isn't 80?
