To avoid getting ripped off, always buy from a trusted, certified retailer like We Buy Phones, where you’re guaranteed a high-quality, tested, and certified pre-owned iPhone. These platforms offer warranties and customer support, so you have protection if something goes wrong. Avoid too-good-to-be-true deals on Facebook Marketplace, Gumtree, or Junk Mail, as these are hotspots for scams. If you’re unsure, check for things like certification, reviews, and the seller’s history before making any transactions.
