Hi I got my phone under the Apple Upgrade Program, before the Sim Free version was available. Verizon is my carrier and I don't plan on leaving in the near term. Is there any advantage to me if having the Sim Free phone? As I understand things, both phones are unlocked. I am still within my return period. However, I have some reluctance to return the phone as my current 6S Plus is without issues. Is there enough advantage to the Sim Free phone, to face the possibility that my new phone will have issues?
