Q: Can I activate a prepaid smartphone on my existing, in-contract, account?

A: Prepaid phones can be activated onto a Postpay account once they've spent at least 6 months active on a Prepay account. You can check any Device ID at http://vz.to/U2wgl6 to see what services it can be used on and even activate it at http://vz.to/186e0Pr.
