Boyfriend broke up with me, wants to take phone?

My boyfriend put me on his phone plan 3 years ago (been dating 5) we went to sprint and we got iphones. I think hes was still paying them off. But now he wants to break up with me and take the phone… Can he just take the phone, it was a gift but then again its still not owned to us yet. Is there anyway i can't keep my phone in this situation?

Change your plan

IT is NOT your phone LEGALLY.
you can b SUED $$$ and lose it.
Get over it simple.
Give it back to him
