Unfortunately, even technically more advanced mobile telephony cannot guarantee you protection from telephone scams and calls from subscribers you do not want to talk to. If you need to block an incoming call to Nokia, you can do it in several ways.
Instructions
Step 1
The easiest way to block unwanted incoming calls will be if your phone has a built-in "Black List" function. Read the user manual for your phone and activate this function by following the instructions.
Step 2
In Nokia smartphones, even if there is no such built-in function, implement the "Black List" programmatically. On the Internet you can find many free programs like Call Manager, Advanced Call Manager, MCleaner. Check if this software is compatible with your smartphone model, download it and install it as an app. The subscriber who will be included in your "Black List" dialing your number will only be able to hear the busy tone.
Step 3
If you are a subscriber of Megafon or Skylink, install the Black List service by contacting the offices of these companies or by asking the operators for the text and short number to which you will need to send an SMS message. This service is paid, but it is inexpensive - the monthly payment is about 30 rubles.
Step 4
But the owners of ordinary, non-multifunctional Nokia devices shouldn't despair either. Create a group in the Contacts menu to which you will assign those subscribers you want to avoid communicating with. In the group settings, set the melody "mute" and you will not hear calls from them. True, in the "Unanswered calls" there will be a list of those phones, the owners of which did not manage to hear your: "Hello!"
Step 5
You won't be able to block an incoming call on a regular Nokia phone, but you can use the call forwarding function. Specify in the forwarding settings any non-existent phone number, for example, one consisting of fewer digits. And the unwanted interlocutor will constantly hear in the receiver: "The number you dialed does not exist."
