So I've been thinking of adding a new line with a new phone (not sure which yet) and taking that phone and putting it on my line. Replacing said phone with a dummy phone I can give to my mom for emergencies. Am I allowed to do that? I've seen that with Amazon, if I do anything to that line they'll charge me some type of fee. Can I buy a phone from the Verizon Corp store and do that? Only reason I want to do that is because I have another year until my upgrade and I'm getting tired of my phone.
