The website seems to force you to buy a new prepaid plan when buying a device. I have an existing prepaid phone (Moto G) that I've had for more than two years, and I simply want to buy a new phone and keep the same number and plan. I don't see why Verizon makes this so difficult for loyal prepaid customers, when it is such an easy process for contract customers. I want to BUY (pay you money) for a new phone. Why is that so difficult?
