Code 0303 is for the exclusive use of telemarketing calls. In addition, it came to facilitate identification, since the number will have to be explicit on the smartphone screen and cannot be an “unknown number”. This will avoid that problem of avoiding answering a call because we already imagine being a boring telemarketer, when, in fact, it could be something important.
It is important to warn, however, that many of these calls are used as a fraud tool and use numbers as a means to do so, known as spoofing. In these cases, it is important to always check the number and if there is an inconsistency, the company about the fraud on the number.
Anatel is already aware of the problem and has already established an anti-fraud group to deal with these cases, which are generally made by robots.
Finally, it is important to warn that even with the novelty that will facilitate and make everything more transparent, you can still use “classic” means such as the Do not disturb me, or else apps to block telemarketing calls.
