Hello 
I had a Verizon SIM card in my old iPad 2 installed a couple of years ago. A few months ago, my iPad died and I replaced it with an iPad Air 2. I never got around to activating cellular data on the new device, nor canceling the old plan (life got in the way). Can I just pop the old SIM card into the new iPad or do I need a new one/new plan?
Thank you!
