sprint I-phone on Verizon's network

I have an early I-phone 5 made for sprint and I need it to work on the Verizon network. Because it was made before the mandate date, Sprint isn't required to send a letter to Apple to say go ahead and unlock it to work on the Verizon network.

Can you help me????

Thanks

here's what I was trying to explain, My I-phone 5 was pre-Feb 2015 sprint isn't able to unlock the sim.

They had me call Apple and Apple told me the Sprint would need to send them a form requesting them to unlock / or reprogram the phone so I could use it on Verizon's network.

For domestic SIM unlockable ("DSU") devices launched after February 2015, Sprint will automatically unlock the device when it becomes eligible. Please note that a domestic SIM unlock will also enable your device to be used internationally using a foreign carrier's SIM card.

For inactive devices, customers must contact Sprint Customer Care to request that their DSU-capable device be unlocked and may have to take steps to perform an over-the-air update to ensure the unlock programming has been relayed to the device. Additional validation may be required to ensure eligibility.

Sprint makes no guaranty that an unlocked device will work on another carrier's network. Whether another carrier will accept and activate a device is subject to that carrier's policies and capabilities. Additionally, Sprint devices which the owner has attempted to reprogram or activate on another carrier's network or otherwise altered from its initial programming or settings may not be able to be reactivated on the Sprint network.
