    Are you tired of the constant phone calls from call centers who want to sell you a service or product at any cost every day? If you are really exhausted you will have to resort to repairs and blocking calls from call centers as soon as possible. If you don't know with the right app you can put an end to business calls from call centers on your home line or smartphone.

    block calls from call centers and stem the phenomenon, you can use the Public Register of Oppositions established by the Ministry of Economic Development. This is a service that allows users in telephone directories to subscribe and exclude themselves from the lists of telemarketers asking not to be disturbed anymore.

    The biggest flaw of the service Public Register of Oppositions is that it does not prevent calls from call centers when the user has given express consent to receive promotional communications. Furthermore, it does not include mobile users who, like the fixed ones, are constantly bombarded by phone calls or SMS from telephone operators and so on.


    Therefore? Mobile devices Android e iOS integrate a function capable of blocking calls from call centers, and therefore the more annoying numbers, but in some cases it is better to use third-party apps.

    Among the many Truecaller allows you to access a list of telemarketing operators in real time to block them from leaving.
