A:AnswerI don’t think you can add storage to your iPad but you can get as much storage as you want by using iCloud for a dollar or two. No ports to connect other devices.
A:AnswerGo to whatever app you want to cast, for example Sling. Open Sling, then top right (typically) there is a cast icon (square with lines on left-looks like a tv). Click it! It should cast to your smart tv.
Make sure everything is on the same Wi-Fi network
A:AnswerI also have Spectrum wifi, if you are not buying an "LTE" version (meaning it works with cellular networks) then they are not categorized to a carrier or being unlocked. Every IPad will work with any wireless network.
