If the device is not connected to any WiFi network it will not be accessible at all :) Probably using GPRS or EDGE you'll release "some" IP address but you won't be able to access the phone using this address. For my suggestion is to connect the device to a WiFi and afterwards to connect to the phone using the received (or the static, depends on the WiFi configuration) address...
