Can i use 1 verizon music essentials kit for 2 differant brand phones to download music to?

Answer 1

The kits inlcude a data cable and software program.
No. Each brand has their own software and different data port jacks. As a matter of fact, even within a brand, you may not be able to share the same kit because of differences in series.

Answer 2

As longs as the brand is still VERIZON you can use the kit for any vcast capable phone.... if you are referring to other companys brand the answer is no the kit includes the usb cable you need to sync from your pc to your phone "any vzw phone" the software and headphone
