What Impacts Your Final Trade-In Price?

To get the most accurate offer, we assess:

• Device condition – new, lightly used, or used
  
  

• Functionality – must fully operate
  
  

• Unlocked vs locked – unlocked phones are typically worth more
  
  

• Accessories – not required, but a charger or box may slightly raise your offer
  
  

• Storage – 1TB is the highest-tier model and commands the best rates

• Beat the seasonal drop in demand
  
  

• Turn a rarely-used luxury phone into real money
