Not all cheap iPhones are the same
Generally, you'll only be able to find the cheapest iPhones in used or refurbished condition. Perhaps you're skeptical about the quality of used iPhones, or maybe you've had a bad experience with a second-hand phone in the past (completely understandable, btw). However, it's important to understand the difference between buying a cheap iPhone used vs buying one refurbished.
Your best option to ensure the best iPhone quality is to make sure you're buying a refurbished one, which means that it has been repaired and tested to the same performing standard as a new phone. These will often be backed by a guarantee or warranty as well.
On the other hand, buying a used iPhone won't guarantee its performance. You need to be careful that you're not buying from an unqualified seller. There are plenty of online marketplaces for used tech, but most don't have any quality control, so the quality can vary wildly.
Before you buy a discounted iPhone online, do a little digging into the marketplace and seller. Check out some reviews, read up on the return policy (if there is one), and find out whether your device comes with any warranties. Trading in your current device can also provide financial benefits and contribute to environmental sustainability when upgrading to a refurbished iPhone.
