I have a Verizon iPad 3rd Gen that I have connected to my Verizon Family Share plan for $10/month (I own it outright, no contract). I would like to upgrade to the iPad Air and let my wife and kids use my old iPad. Can I do the following: 1) Buy a new iPad Air at T-Mobile and sign up of the 1GB of LTE for $10/mo 2) Immediately go home and swap the SIM cards of this T-Mobile iPad with my Verizon 3rd Gen iPad? This would allow me to get the T-Mobile discount on the iPad (which is about $130 off) and free financing and it would allow me to have the fast reliable Verizon network on the new iPad and no risk of data overages on the kids' iPad. Would this be as easy as swapping SIM's as soon as I bring home the new device? Is there anything else I should know? Thanks in advance!
