Before you buy
Match the storage, RAM and regional model to the seller listing. Check supported network bands and SIM options with your carrier before choosing an imported unit.
Compare the camera, display and charging specifications with the features you use most. Megapixels and battery capacity alone do not establish photo quality or real-world battery life.
For a used phone, inspect battery health, account locks, display, cameras and charging port. Confirm warranty and the software-update policy for the exact model.
