As far as I know only Bluetooth is used for transmitting the pictures. Even the updates work that way- downloads go to your phone and then to the cam via Bluetooth. That's what I meant by using Wi-Fi for updates, the files can be quite large. Sorry for the confusion.
May want to look into a reasonably priced cell cam like the Tactacam Reveal, monthly plans start at $5. Unless you have the cam by a feeder or something and with a short delay. I'm considering getting another one unless this latest Air update gives it a boost.
