Matters needing attention in mobile phone transaction:

Cash on delivery looks very reliable. Before receiving the goods, we don't have to worry about the swindlers cheating away the money, but the actual situation is that after we receive the mobile phone, we can only look at the quality of the mobile phone roughly and have no idea what is in it. Many people think that cash on delivery merchants are more trustworthy and easy to relax their vigilance. In fact, there are many refurbished machines, and the quality was not bad a few days ago.

In a few days, all kinds of problems appeared. Face-to-face transactions are also risky. Now, in order to improve the success rate of the transaction, some sellers say that they can trade face to face. When the mobile phone is white, face-to-face trading of people and goods is reliable.

But mobile phone buyers generally don't know much about professional mobile phone knowledge. Some refurbished bomb machines look good at the time of trading, but after a few days of use, quality problems will slowly begin to appear. Therefore, strict quality inspection is very important for second-hand mobile phone transactions.
