At this point the only Alltel phones that will work on Verizon are models that Verizon also sells like the Motorola V3m but NOT the V3a, or the K1m, etc. Also the AX8600 uses ESN's still so it won't activate as the VX8600 uses MEID's. The reason these will work on Verizon is due to their ESN/MEID's being loaded into Verizon's DMD already. Obviously you'll have to find a rep that is willing to activate it on Verizon's end. Good luck!

Technically all of the phones will work on verizon. They use the exact same technology. It's just a matter of whether the software on the phone will work. That only means that potentially the axcess apps store may not work. But other then that you should be fine.
