I bought a used one and I would like to find out how much warranty I have if any?
If the warranty is like cell devices, the warranty is good only for the original owner.
The only way you will know for sure is if you contact Verizon and ask.
When I looked at my customer receipt from Verizon I noticed there was a line added for a 1yr MFG Warranty. Chances are that if your customer receipt for activating the device does not include this line then you will not have warranty support for it either.
