They also have Atm like machines where you can sell your used phones, laptops, and tablets. They must be.in working condition and be prepared to prove that it does. They also need to be yours not stolen as well as if you have a contract and you didn't pay it off then it cannot be serviced again and they check the IMEI numbers etc. Its called Eco Atm I believe
On facebook marketplace, ksl or someplace similar... Not sure you can sale it in the mall...
