recently bought a new phone from a friend and gave away his old phone. This is a good thing, but today she suddenly sent a message to tell me that she had forgotten to unbind the bank card of the old mobile phone. Is there a risk? After I listened, I told her that I didn't have to worry about this problem at all. Next, I will talk about my views in detail.
Is there any risk in giving away an old mobile phone?
I personally think that giving away an old mobile phone is risky. First, let's look at what information and data the mobile phone itself stores? Let's start with 2G mobile phones. Old mobile phones generally save things like address books, text messages, photos, and videos. If you did not restore the old phone to factory settings, you did not delete the above stuff. Then you will face information leakage. Speaking of today's smart phones, similarly, there are also contacts, text messages, photos and videos, as well as various apps, chat information, bank cards and so on. Will these apps be at risk of leaking?
passed my field test and took out the phone card. Some apps that do not require a password for login can be accessed directly, such as chat apps and shopping apps. Some apps that require a login password are not accessible, such as banking apps, certain cloud, etc. However, in the shopping app mentioned earlier, you still need to enter the payment password in the payment link to complete the payment. From the perspective of fund security, there is no need to worry about the risk of funds after the old mobile phone is given away. Of course, except for the case where you give it away with your phone card. Before giving away your old phone, try to restore the phone to factory settings. After performing this operation, the phone will delete all the data and apps on it. It's the same as the mobile phone you just got, without any personal information or information about you. How to replace the new mobile phone scientifically? Then look down.
What should I do if I change a new mobile phone?
First, synchronize the data of the old phone to the new phone. If it is a mobile phone of the same brand, data can be transferred through the brand’s synchronization app. Mobile phones of different brands can also be transferred online through a third-party sync app. Simply put, you first install a third-party app on your old phone, and use it to synchronize the old phone's data to the Internet. Then install the same app on the new phone, and then download the online synchronized data to the new phone through it. This completes the synchronization of the old phone to the new phone.
Next, you need to install all the apps of the old phone to the new phone, and log in to the new phone through the old phone. For example: when you install a letter, you will be asked to verify the information of the new phone on the old phone, and then you can log in on the new phone after passing it. Be sure to log in all apps on the new phone, remember!
Finally, go to the device management of app security management and delete the login record of the old phone. This is very important. The chat app and shopping app mentioned earlier can log in without a password, which is why it is not deleted here. After you delete the old phone's record, the old phone can no longer log in directly.
has completed the above three steps and basically replaced it with a new phone. At this time, you can restore the old phone to factory settings. In addition to changing your phone, you should also develop some safety habits when using your phone.
Develop a safe mobile phone usage habit
The most important thing for mobile phone security habits is to set the sim card password. Simply put, the function of the sim card password is to enter the password every time you turn on the phone. With it, you don’t have to worry about your sim card being taken by others to receive SMS verification codes if you lose your phone. This is very important and it is deliberately put first.
Second, you must set a lock screen password. Today's smart phones are more of a symbol of oneself, with personal privacy inside. Set a complex lock screen password, you can add a lock for personal privacy. Although it is not 100% safe, there is always no strong.
bought a new mobile phone and gave away the old mobile phone, but did not untie the bank card, so don't worry at all. You can use the new phone to unbind the old phone device. In addition, when it comes to fund payment, it is necessary to enter a payment password. Others don’t know your password, so don’t worry about it at all.
