What is Warranty length?
In short
A warranty length is how many months a retailer covers a phone or refurbished device before a repair is yours to pay for.
A warranty is the retailer's promise to cover faults in a device, and its length is counted in months from delivery. It carries the most weight on refurbished stock, where buyers take on a device that has already been used, and longer cover cuts the risk of paying for a replacement part. asgoodasnew offers the longest run in this group at 30 months. AGM Mobile, ALTERNATE in Spain and Back Market each cover 12 months, while BuyDig offers 3 months.
