Can I use a used iPhone on a different carrier?

I was thinking of buying a used iPhone but I have Virgin Mobile (which does carry iPhones) and the last carrier was different. Would they still activate the iPhone even though it's not from Virgin Mobile?
I thought iPhones could since they use a different operating system but I didn't want to go through with the purchase without knowing. If for some reason I would NOT be able to activate a used iphone, is there a way around it?

No, virgin mobile will not activate any iphones except virgin mobile iphones.

If this was the case with a GSM carrier it would have been possible, since you'd just have to get an unlock for it.
But, since Virgin Mobile is CDMA, you wouldn't have that option. As the other answerer said they wouldn't activate it.

It is not possible to use an iPhone that is not made for Virgin Mobile on Virgin Mobile, the iPhones are carrier specific. You can probably find a used Virgin Mobile iPhone somewhere. There's a way around this, but its not legal.

  • Two different computers, two different iTunes.can I use the same Apple ID? I have iTunes on my computer that I use for my iPhone, and my mon just got an iPod Touch and wants me to fill it for her. I'm going to use her computer to do this, which currently does not have iTunes. Once I download iTunes, can I use my own Apple ID to download songs and apps onto her iPod? Is it possible to do that without disturbing what's on my phone, or do I have to make a whole new iTunes account for her?
  • If I have a iPhone 6s, could i use more than one carrier at different times? So I'm thinking about switching to Sprint. At the moment i have a iPhone 5 with a AT&T prepaid sim in it. If I get a Sprint iPhone, would i be able to switch to my prepaid one and not get in trouble? (At&t has service at my cabin, sprint does not)
  • If I buy an iphone used from another carrier ad buy a sim card from my carrier will that work? I have an iphone 4s with virgin mobile and I want an iphone 5 but all virgin mobile phones are so expensive! I looked on ebay for virgin mobile nano sim cards and they are only around 2 dollars. If I bought one of these sim cards and a used iphone 5 from another carrier would it work with my carrier?
  • Can you watch netflix on two different TV s in different homes? We can watch Netflix on our Wii, computer, and iPod/iPhone. But I was wondering if you can watch them on 2 different TV's in different houses. So can we be signed into the Wii at my house, and signed into the Bluray player at my grandparents house so we can watch it there too, for no extra charge (The same account)?
