On the cellular model of the iPad Pro, will photos be automatically (accurately) GPS tagged even when NOT using a SIM card? I plan to use my iPad pro without any SIM card/data service but am be interested in buying the cellular model only because I want to be able to always accurately GPS tag the photos I take with it. Will the GPS tagging happen when I take photos without a SIM card in the iPad? If not, are there other (easy to implement) ways for that data to automatically get tagged on the photos I take? (maybe through the Apple Watch or iPhone)?
