To avoid endless threads asking the same question as to whether Verizon can activate a Sprint phone (of any kind), or a phone from MetroPCS, Cricket, US Cellular or Grandma's Cellular, below is the answer given each time this question is asked: Verizon will not activate any phone they do not sell, even if the same model is carried by any CDMA network competitor, like Sprint or Alltel. Though this is not absolute, the likelihood of them activating a non-Verizon phone is slim to none. Even if you get lucky and are able to do it, you are fortunate because a Verizon employee did something they are not supposed to do. The time and effort it would take to try and activate a non-Verizon phone with Verizon is not worth the bother. Sell your other-carrier phone and buy the Verizon version. Another important point to make is Verizon and Sprint, in particular, have their own user interface they use with on phones to personalize it to the carrier's options and standards. A phone would need to be "flashed" in order to even be able to be used on another carrier. If you don't know what "flashing a phone" means, you shouldn't bother doing it. You would really have to know how to do it properly and even then, the time and effort is not worth the bother AND you run the risk of killing the phone, otherwise relegating it to a paper-weight or door-stopper. Besides, you would not have access to several Verizon features because you do not have their options programmed into the phone. Flashing doesn't guarantee it will work with Verizon either. "Unlocking" a phone is irrelevant to CDMA carriers, like Verizon. Unlocking is most useful for GSM carriers like AT&T and T-Mobile, as unlocking your phone allows you to use it on any GSM network. The bottom line is there is no guarantee Verizon will activate a CDMA phone they haven't sold, regardless where it's from. Hopefully this answers a question you are about to ask as a new thread.
