I could use some informed instruction on how to use my iPad 2 to fly my Mavic Pro instead of my company cell phone. For obvious reasons I do not want to use the cell phone and bought an iPad 2 to use instead. I don't have a personal cell phone or service since the company has been providing one for the last 18 years. Can I just sign up for a Mint Mobile $15 monthly cell plan to get a sim card to install in the iPad and go on down the road? Do I even need a sim card? Any suggestions on if I'm doing this right would be appreciated. I'm older and a little concerned on flying and want to make sure I don't make a FUBAR mistake by not being able to control it effectively using the iPad and a wireless sim card.
