Hi BG,
Thank you for reaching out. I appreciate your concern regarding the warranty of the Galaxy S10 (Unlocked). Typically, devices only have one year warranty, but if you recently purchased the device, we will need the bill of purchase to honor the warranty.
Please refer to this link for more information under "Standard Limited Warranty":
