Trying to get a little help with my new Galaxy note 3. I am upgrading from the sprint note 2 (which i still love) and getting into a note 3. I have an old plan with Sprint that gives me unlimited everything on 2 devices for $100 per month. They are refusing to let me upgrade and keep my current pan. So I decided to buy a used phone off ebay (refurbished from a professional) I was under the assumption that I could use any CDMA phone and it would work on the sprint network so I ordered a Verizon Note 3. I'm also a bit new to sim cards, so I had to go to the Sprint corporate store to get one. Once there they informed me that this phone would not work on the sprint network and that they could not activate the phone on my sprint account. I asked why a CDMA phone wouldnt work on a CDMA network. and the guy at the desk said that the verizon phone had totally different antennas and uses a completely different technology than the Sprint phones did. Was this guy just lying to me or is this true. please help.
