I called about transferring and they said I had to wait until my alltel contract was up. I figured they would let me transfer early to eliminate the old alltel customers and plans.
And if that method doesn't work for you, you will be able to upgrade to a new phone without the ETF 120 days before the end of your contract. But you will have to change to a Verizon plan. You will not be able to keep your Alltel plan with a Verizon device.
