Who has a mobile phone number modifier?

Modifier can't exist, because it violates the relevant regulations of a communication, but it may be available if it is a relay function to cover up the real number of a mobile phone, that is, each mobile phone user automatically sets his own calling card and then realizes the relay of that phone, but this relay phone needs to input another phone number by himself, so when someone calls, the phone will automatically transfer to this filled-in number to cover up the real number. Of course, the function of covering up the real number does not mean directly changing the telephone number, but a purpose of covering up the real communication between this number and another number.

For me, it is impossible to modify the mobile phone number directly, because most mobile phone cards and numbers are handled through real-name registration system, which is a service channel. If you really want to change the number, you have to apply for a new mobile phone card and then change the mobile phone number, so that most mobile phone cards are actually handled by real names, and a few are treated as one-time calls. Only those black cards with invalid numbers can be said to use or change new numbers frequently, but in fact, these real principles have nothing to do with number change, so it is impossible to change the number at present, but if you change the number, you can choose to change the number with a mobile phone calling card or use the local broadcasting function of the mobile phone to broadcast.

This kind of relay function is recommended to be used with caution. After all, if an important call comes in, it is likely that the call will call the phone number of another person who wants to call back. If this phone number is not set to cancel this setting, then no matter how many times you dial it, you will go to this number instead of directly going to the original phone number, and over time, a dialing cycle of the two numbers will be chaotic to some extent.
