Yeah, I was forced to upgrade my verizon sim on my last iPad and they made me activate it and it sucked because from that point on I could not manage the monthly billing (or choice to cancel it) on the iPad directly like all the other ones. You had to use the online verizon web login. Very inconvenient. I was planning on using verizon but they buried the Free Verizon SIM option in all the "extras" after you skipped the engraving option. All I saw was the big green "Add to Bag" button at the bottom of the webpage and clicked it not knowing the verizon sim was optional.
