So I have an HTC M8 in red that I used Edge on. I have since bought a Nexus 6 unlocked and have used for almost a year now. I believe I still have an Edge balance on the M8 and wanted to sell it along with the Nexus to pick up a Moto X. Would you guys happen to know if I need to pay that blaance first before I sell the M8? I was just going to funnel the cash over to the Edge balance unless I have to pay it first.
