Message+ on old phone

tractor1

I have replaced my Droid Maxx, but want to use it with Verizon Message+. It synchronized my old messages fine, but I can't send or receive new ones. It sent a text to my new phone with a code, but I can't find a place to manually enter it on my old phone.

Tidbits

If it's on wifi and setup I believe the other phone can access it. I believe you have to turn it off then factory reset the phone and it would make sure no one can turn it back on.
