I just recently bought a refurbished "Verizon" IPhone 7 plus black 128gb (BestBuy). Called Virgin to tell them I wanted to use it as my new phone, they obliged. They asked for the IMEI to make sure it wasn't stolen, and to make sure it was compatible on the network. It wasn't stolen and was compatible. They Carrier unlocked it, told me to go get a sim from Sprint for it and call back. Got the sim, called them back, they activated it, switched my number over and voila. No issues, no problems everything works great.
