What is a refurbished phone?

A refurbished phone is a pre-owned device that has been professionally tested, repaired if needed, cleaned, and restored to full working condition. At Zextons it is sold with a cosmetic grade and warranty.

What battery health will my refurbished phone have?

Refurbished Apple iPhones supplied by Zextons have a minimum battery health of 85%. Other phones are tested to the manufacturer's standards. This does not mean every device has a brand-new battery or 100% battery health.

Do your refurbished phones come with a warranty?

Yes. Refurbished phones typically include an 18-month Zextons warranty, subject to the warranty terms on the listing.

What is the difference between Excellent, Good and Fair condition?

These grades describe cosmetic condition. Excellent has minimal marks, Good has light cosmetic wear, and Fair has visible cosmetic wear. All grades undergo a 70+ point inspection to check functionality before sale.

Are your phones unlocked?

Yes. Unless otherwise stated, all phones are fully unlocked and compatible with UK networks including Vodafone, O2, EE, and Three.

What accessories come with the phone?

Refurbished phones include a charging cable, SIM tool, and Protection bundle where stated. A charger plug is included only when listed on the product. Packaging may not be original.
