АнтиЗвонарь АОН

The application simply shows the operator and the region of the caller, reject or accept - it's up to you.

The decision to talk or decline is yours.

Nothing fancy, no SPAM fantasies or blocking decisions for you.

The application does not take up resources, it is activated only when called by a system event on your phone.

Allows you to determine the telecom operator (for example, MTS, Megafon, Beeline, Rostelecom, etc.) and the region (city, region, region) when calling from an unknown phone number, Caller ID mode.

It works in the background (service) mode, it is enough to run it once.

Information on the phone number is also relevant if it was transferred from one mobile operator to another operator via MNP.

Functions are saved even after rebooting the phone.

Caller ID is triggered if the number is unknown (not recorded by you).
