By default Cell Widget does not transmit any data to the internet.
If you enable the “Auto save new cells”-feature, each new mobile cell will be sent to an google service to get the coordinates (latitude and longitude) for the location id and cell id of the cell. Additionally, the coordinates received will be reverse geocoded to get a readable address
