iCloud Locked - a unique lock to iPads and iPhones with the release of iOS 7. If the phone is not deleted from a previous user's account before it is sold or disposed of, then it will be locked to that user's account and no one can use it.
Unless otherwise stated, all units have been factory reset and are free of Apple activation lock/iCloud lock.
Is the unit carrier locked?
Unless otherwise stated, the buyer should assume that the phones are locked to the carrier they are listed for (i.e. AT&T, T-Mobile, Sprint).
All Verizon 4G LTE devices are factory unlocked for use on the Verizon network or any GSM network. Please note, most Sprint units are not GSM capable.
