Is it possible to factory unlock a verizon iphone 4s with bad esn to tmobile?

I have a bad esn verizon iphone 4s and was wondering if i can factory unlock it so i can use it on tmobile.

No, only att 4s will work on tmobile.
i have 1 for sale or trade if your in PA.
email me

It is not possible sorry.

No you can't.

First, unlocking Verizon is not possible with bad ESN.
Second, unlocked Verizon iPhone doesn't accept US SIM, for overseas use only.
