I use Nokia 1600 SMS, which has a network command editor. I don't know what this is for, but who knows?

Through this function, you can send commands to network service providers to provide certain network services, such as starting services, weather forecast, road information, etc. After receiving your service request, the service provider will send you the service content you requested by SMS. This feature requires network support. Please ask your service provider whether your network supports this function, the contents of available services, the contents of commands and other related matters.
