If you have a broken or outdated phone but do not want to spend too much on a replacement phone, you should consider buying a used phone instead. However, just like in buying any used electronics, there are a few pros and cons to buying a used mobile phone.

PROS
AFFORDABLE PRICES.When you purchase a used phone, you can get big savings as much as 20% to 50% compared to buying brand new ones. Additionally, with all the people replacing their handsets after only about six months, you can get a nearly new device for a good bargain.
COMMITMENT FREE.When you purchase a used phone, you purchase it outright rather than get it from a carrier under a contract. This means no lock-in period, which is great if you hate commitments. While you can use the phone on a pay as you go basis, you are also free to use it with a sim only contract for you to get the most savings, as long as the phone is compatible with your chosen provider.
ENVIRONMENT FRIENDLY.Most of us don’t really know how to recycle old mobile devices, and are unaware of the potential environment hazards their chemical components could bring. By buying a used phone, we can help reduce the number of phones which are improperly disposed and ultimately protect our environment.

CONS
WEAR AND TEAR.Obviously, when you purchase a used mobile, you can’t expect it to be in perfect condition. While you may be lucky if you landed on a phone with nothing except a few minor scratches, they may still be pretty costly. Because of the obvious deterioration in a second hand mobile’s physical appearance, they are not recommended to be bought as gifts.
SHORTENED WARRANTY.When you buy a brand new phone, you will typically be given a one-year service warranty from the manufacturer, so that they could either repair or replace a defective phone for free. On the other hand, when you buy a used phone, you will only be eligible for a short (usually 30 days) warranty if you bought directly from service providers. The downside with this is that you will also be locked to using only a sim card from that provider. Additionally, the phones they sell are still quite costly as compared to other third party vendors or individual sellers. Meanwhile, you can save a lot of cash and even bargain when you transact with an individual seller, but the result is that you might not be given any warranty at all.
LACK OF FULL DISCLOSURE.Buying any second hand item is like a gamble. You wouldn’t know what to expect, unless you’re fortunate enough to encounter an honest seller who tells you every minor detail and issue about your phone. But chances are, you’ll never know if the phone has had any previous problems. It may look good on the outside, but there might be an underlying problem within its hardware that you didn’t have the chance to discover during your test.
THE VERDICT
Buying a second hand phone does have its ups and downs. If you take the time exploring your options and giving each a careful consideration, you can land a good deal and get a decent phone for a bargain. However, if you’re not careful, you might end up wasting more money by buying a defective gadget.
