Network address book is an application/service that uses the Internet or realizes network storage and backup of address book. One of the most important functions of the network address book is to synchronize the contact information between different devices. For example, you can enter the information of a contact person on a computer, and then read or modify the information on a mobile phone or another computer.

Of course, you can also enter your contact's phone number, email address, QQ, MSN, mailing address and other address book information on your personal computer, or group, manage and update previous information. With your permission, contacts can see the information of other contacts in their own group, so as to realize the * * * sharing of the address book. You can also directly call and send text messages to family, friends and colleagues through the network address book.

3. How to know the mobile phone verification code

Imei (International Mobile Equipment Identification Code) is the abbreviation of international mobile equipment identification code, which is an "electronic serial number" composed of 15 digits, corresponding to each mobile phone one by one, and the code is unique in the world. Every mobile phone will be given a unique group number in the world after assembly, and this number will be recorded by the manufacturer from production to factory.

Press *#06# on your mobile phone and an IMEI code will appear. The first 6 digits (TAC) are "model approval numbers", which generally represent models. The next two digits (FAC) are the "last assembly number", which generally represents the place of origin. The 6-digit number (SNR) is followed by the "serial number", which generally represents the production serial number. Finally, 1 bit (SP) is usually "0", which is a check code and is reserved for the time being.

For example, the IMEI of a GT-I9308 mobile phone of Samsung is: 35506505331101. Where 355065 is TAC, 05 is FAC, 33 1 100 is SNR, 1 is SP, and 0 1 is the software version number.

The IMEI code is attached to the sign on the back of the mobile phone and read and write in the memory of the mobile phone. It is also the "document" and "ID number" of the mobile phone in the manufacturer.

4. How to get the verification code of someone else's mobile phone number?

The mobile phone verification code is used for anti-theft. If it is easy to verify, what can be believed? Here's what happens if it is, but it can't be realized.

1. If the mobile phone number is copied, the last one who turns on the phone, or dials the phone at intervals, or contacts the website at intervals, can receive the text message, but the other one can't. The current card cannot be copied, and reading the lock code will burn the card, which means it is impossible now.

2. First of all, let me talk about the certification body. The verification code issued by general banks is strict, and the server is encrypted by multiple layers. There is also a record, that is, if you send a verification application with any network address, the other party has a record, and then the verification code is sent to the designated mobile phone. Mobile phones can't be intercepted, and the network is even more impossible.

3. Some small websites, including mobile phone authentication institutions, authenticate through their platforms and give you a port. For example, if you make a website, when the other party logs in, you will send a number to the certification body, and the certification body will send this number to the designated mobile phone through the network. In order not to be intercepted, the instructions are encrypted, but this organization can definitely decode them, but they won't give you the source code, because once the source code is made public, their certification organization will be paralyzed and hackers will attack.
