Is the old phone kept or sold, and how is it the most cost effective to sell the old phone?

All good.

Because now mobile phones are launched every year, and the old mobile phones are idle after changing to a new one. There are two ways to deal with old phones:

Keep it for yourself or for your parents, and sell it for money.

We require the performance of the mobile phone to be good, so if there is a new mobile phone, replace it, the performance of the old mobile phone may not be able to catch up with the new mobile phone, but for parents who do not have high performance requirements, the old mobile phone can be used again. You can also sell your old mobile phone to a reliable second-hand platform for money to improve your economy.

Don't throw away or sell your old phone at will, you can go to the official after-sales or business hall store of the mobile phone brand, let the professional clear the data information, and be vigilant in the removal process.

Of course, the old mobile phones that are idle and piled up at home need to be disposed of urgently, not only because the waste machine poses a fatal threat to the natural environment and physical and mental health, but also because the waste machine also contains a lot of valuable recycled materials.

Related Notes:

First, refurbishment and selling parts. Hawkers will classify the mobile phones according to different brands and new and old, if they are particularly good, they will be sold directly to the mobile phone store, and then refurbished, and the others will take out the parts that can be used in the mobile phone, and these parts are sold to the mobile phone store is much higher than the cost of **.

Second, refinement. Mobile phones contain rare metals.

**The old mobile phone can be refined by technical means of rare metals, if the refining is more valuable, it is not a lot, which is generally for the **** relatively low mobile phone to deal with.

Third, refinement. According to relevant reports, 160 grams can be extracted from a mobile phone**, which is also quite a good ratio.

Fourth, reselling personal information. In fact, there is a lot of personal information in the old mobile phone, and the information will not be deleted before selling the mobile phone, especially for the elderly, the awareness of protecting information is not strong, and the personal information can be restored and extracted through technical means, and these personal information can be sold, so the information of the old mobile phone should be deleted and then sold.

If you want to sell your old phone and get the best deal**, here are a few possible ways to do it:

Xianyu: Xianyu is a very popular second-hand trading platform, and many people will ** old mobile phones on it. Here, you can post your mobile ad, set up yours**, and wait for interested buyers to contact you.

Second-hand phone stores: There are many second-hand phone stores in China, and these stores usually buy old phones and then resell them. This can be a good option if your phone is in good condition. However, due to the need for stores to guarantee profits, the ** may be relatively low.

Second-hand trading platform: In addition to Xianyu, there are many other second-hand trading platforms, such as turning, catching markets, etc. You can advertise on these platforms and ** your phone.

Moments: If you have a lot of friends and they might be interested in your phone, you can post ads in your moments. This may be simpler, but there are some security issues to be aware of, such as how to protect your privacy and prevent fraud.

Whichever method you choose, you need to take care to protect your security and privacy. Know as much as possible the background of the buyer or ** company and make sure there is a written agreement in place during the transaction.

There may be the following reasons:

1.The old mobile phone stores a lot of personal information, and if it is sold to an unreliable ** business, it may lead to privacy leakage, and even encounter fraud or theft. Even if you do a factory reset, you can't completely erase the data, and you need some special methods to erase it completely.

2.The price of old mobile phones is very low, and many people feel that it is not worth selling. This is because the merchant needs to consider the depreciation of the mobile phone, inventory, channels and other costs, so the ** given is much lower than the market price.

Old mobile phones can also be used for other purposes, such as car navigation systems, dash cams, home monitors, universal remote controls, etc. Some people also keep their old phones as a backup or collectible.

4.Old mobile phones have a certain emotional value, such as being a gift for yourself or others, or recording some important memories that you are reluctant to sell.

Because I am reluctant to carry the memories at the same time, a lot of practical documents are saved in the mobile phone, and the mobile phone number is a must for individuals.

Old phones can also work, as long as they are not too bad.

I don't think valuations are too low to have the will to sell.

There are safe ways to dispose of old mobile phones before selling them

1. Give the old phone a buffer period for a period of time.

Reducing the amount and frequency of information stored during this period can reduce some of the hidden dangers. Even if the information related to payment is reduced in use, even if it is later restored, the harm caused will be significantly reduced. This is because some payment platform versions are updated very quickly, and the old version is generally isolated from the new version.

Even if some important information is recovered in the future, it may not be available on the current platform. But we still have to be vigilant, after all, many people will upload their documents** to the platform and Chazi. Once these things are recovered, although they have no impact on our payments, they still pose a certain threat to personal privacy information and financial security.

2. Avoid mobile phone information leakage.

First of all, we don't want to deal with mobile phones in small stores, if we want to deal with them, we will go to a regular store to deal with them. If you want to sell your old phone, you should pay more attention to this, in addition to restoring factory settings and completely deleting old files, you can also use some smashing software in the application market. Repetitive operations for file deletion are doubly insured.

3. Connect the old mobile phone with the computer.

After deleting important files, store the useless files back on your smartphone. Thirdly, the chances of being able to recover the original important information will be greatly reduced by deleting the original important information that has been designed to be overwritten multiple times.

Online or offline.

Now there are many places to sell second-hand mobile phones, such as the most common online places are salted fish, Zhuan Zhuan, Jingdong second-hand, 58.com, etc., and you can also go to mobile phone repair shops to sell offline.

It is often rumored on the Internet that you will take away your used phone to steal your personal privacy, in fact, we ordinary people do not have any privacy to steal, and there is no need to steal it, you think about how troublesome data recovery is.

Even if there is no useful information in the recovery, unless you are a big boss, the boss, the data recovery, maybe there is information that can be used. We only need to factory reset the phone several times repeatedly, and we can completely erase our own information. <>
