How and where to sell old cell phones to get good price back?

Hi, put them all on e-bay. This is the quick and easy way to sell cell phone as I work for such type of company I have liquidated many of the old cell phone. You don’t have to worry about it when you have some latest cell phone as some time many even oldest and broken cells are being purchased just for recycling their parts .Its ok that you have NOKIA, MOTOROLA, And SAMSUNG but I don’t know they are locked or unlocked ones, if they are locked then try to unlock them all because unlocked cell phone can be sold worldwide. This thing does not apply with your locked ones , they are to be sold within the local area as they are in contract with local carrier or service providers.Here you will get real value for your cell phone and you need not to go after your friends for selling them all.
