All phones sold by Wakephone are original used phones, all from legal and formal channels. We graded our phones based on their appearance from A+ to C because EACH phone has passed the test of our professional technicians with phone testing software and the function is 100% works. All used phones undergo detailed tests by PhoneCheck to ensure all IMEI is cleaned, with no omissions. All phones are unlocked, clean, no contracts, and ready to go.
