I hope this is the correct place for my question. If not please redirect me. During the recent power outage I realized that if I signed up for cellular data access I would be able to communicate with the world in some manner. However, I feel that I do not really understand what I am doing. What I do understand is that if I have no power and no wifi service I will be able to connect through my cellular data account. What happens when my wifi service becomes active again? Is it correct that unless I turn off the cellular data service that it will continue to be used like wifi instead of using my wifi service? My iPad was set to cellular data ON, Enable LTE set to ON and roaming set to OFF. I only want to use cellular data when I am away from my own wifi site. Thank you any help and understandin you can give me.
