This is a stupid question and I feel stupid having to ask, but does activating my phones cost money? I currently have 3 Verizon phones, and would like to switch around my primary device for a few days. My question is, does it cost money each time I switch phones? What I usually do is go to the verizon site and say I'm 'upgrading' my phone and de-activate the one while reactivating the other. does this cost money each time, or is it free?
