Saved $100 buying my refurb on a state tax holiday last weekend. 32GB with 4G. Everything works fine but when I tried to activate cellular I got error message. I took it to the Verizon store and they said the serial number is not on their list so I couldn't activate. They had to submit a form and now I have to wait 3 days before I can activate 4G. Anyone else have this happen with refurbs?
