Here's the story: I have sprint and hate it. I practically live at work and get no bars and my data speeds are extremely slow(less than 1 Mbps) so I want to switch to AT&T, where I know the speeds are around 30 Mbps. I have 2 lines with 15 months left on my contract so my ETF are around $300 per line. My plan is to transfer service to 2 dumb phones, wait a month and then cancel the service and pay a ETF of $150 per line. Has anyone ever done this?
