The $25 discount ends one you pay off the device unless you sign up for another Edge plan. I was reluctantly looking to go back to Verizon for the S6 128GB since AT&T just don't have have a date. But now I see the 75% pay off requirement and I'm like are you nuts. Come on, they jacked the ETF policy to where you have to clear 8 months before it starts to discount now the Edge plan is pay off 75% and they keep the device. If you are going to pay off 75% you might as well pay off the balance, keep the phone or sell it. But of course if you pay it off and don't give the phone up to Verizon you can't Edge up for 60 days. Its all in the fine print.
