I registered to share my experience.
I preordered note 7 from verizon website after 2-yr agreement & upgrade current line I am using.
I managed to keep my Unlimited Data Plan along with it.
Went to Corporate Store in PA after
contacted Samsung to raise the ticket on Verizon account.
contacted Verizon to confirm they received the ticket and note was in place.
confirmed with them I can get loaner and get the note 7 when it becomes available.
The staff in the store was informative and kind to explain everything.
He and his manager told me
I can switch to S7 or S7 Edge for now and switch back to Note 7 when It becomes available.
I asked them back what you are saying is 'double swap' and they answered yes.
So I was almost getting my note 7 replaced by s7 edge.
But the unlimited data plan was blocking everything to do so.
The system kept asking pick the data plan or no-go.
The staff was trying everything to keep my unlimited plan and explained everything.
But it could not be done in their level, so I left the store with my note 7 after let them digged into the matter for good hour.
I will try to find the way around or contact customer service for this matter.
By the way, when I tried to return my note7
he asked me if I have box for the phone.
I handed the box with nothing in it, and he never bothered to open the box.
So I will think about the keeping UDT, keeping until Note 7 available, or switch the carrier altogether after complete return
since I don't have any backup device for verizon ...
