The control over who reaches you should be yours
For millions of Brazilians, the uninvited voice on the other end of the line has long been a small but persistent erosion of daily peace. Now, a convergence of native technology, federal regulation, and legal recourse has shifted the balance — placing meaningful control back in the hands of ordinary people. Since September 2025, telecom providers are legally bound to honor consumer opt-outs, and the tools to exercise that right have never been more accessible.
- Millions of Brazilians face repeated, unsolicited telemarketing and loan calls each week, disrupting daily life and disproportionately targeting retirees and pensioners.
- Most consumers are unaware that their own smartphones already carry built-in defenses — iPhone's Silence Unknown Callers and Android's spam filters can stop unknown numbers before they even ring.
- The federal government's Não Me Perturbe service became mandatory for all telecom operators in September 2025, giving consumers a legally enforceable right to refuse unsolicited commercial contact.
- Retirees and civil servants can block consignado loan offers directly through the INSS app or by calling 135, and can audit existing contracts via the Central Bank's Registrato system.
- When harassment persists, the Consumer Protection Code provides legal recourse — documented call records can support complaints at PROCON or small claims court.
Your phone rings again. You set down your coffee, and on the other end is another voice pitching a loan you never requested. For millions of Brazilians, this is a weekly ritual — but most don't realize their phone already carries the tools to end it.
Both iPhone and Android devices include built-in call filtering that most users never find. On iPhone, activating Silence Unknown Callers sends any number outside your contacts straight to voicemail. Android devices — including Samsung, Motorola, and Xiaomi — offer spam filters and can flag suspicious calls with a warning before you answer.
Beyond the phone itself, the federal government's Não Me Perturbe service, regulated by ANATEL, functions as a legal prohibition against unsolicited sales contact. Registration is free and takes minutes. A pivotal change came in September 2025, when ANATEL made compliance mandatory for every telecom provider in Brazil — dramatically expanding the service's reach. Debt collection and fraud prevention calls remain permitted, but unsolicited pitches do not.
Consignado loans warrant particular attention, as they relentlessly target retirees, pensioners, and civil servants. The INSS offers a direct block through its Meu INSS app or via a free call to 135. The Central Bank's Registrato system also lets consumers review every consignado contract linked to their CPF, making unauthorized agreements easier to detect.
When these measures fall short, the Consumer Protection Code classifies persistent unauthorized contact as abusive practice, opening the door to PROCON complaints or small claims court. The key is documentation — saving the number, date, and time of each unwanted call builds the evidentiary record authorities need to act.
For those wanting additional protection, apps like Whoscall and Truecaller cross-reference incoming numbers against live spam databases. Layered together, these tools — native filters, government registration, INSS blocking, and third-party identifiers — form a solid barrier. The control over who reaches you is yours to claim.
Your phone rings. Again. You set down whatever you were doing—coffee, work, a conversation—and on the other end is another cheerful voice pitching a loan you never asked for, a plan you don't want, a service you didn't request. For millions of Brazilians, this happens several times a week. The frustration is real. But there's something most people don't realize: your phone already has the tools to stop it.
Both iPhone and Android devices come with built-in call filtering that most users never discover. On an iPhone, the path is straightforward: Settings → Phone → Silence Unknown Callers. Once activated, any number not in your contacts goes straight to voicemail. Android varies by manufacturer, but the general route is Phone → Menu → Settings → Block Numbers or Spam Filter. Many Samsung, Motorola, and Xiaomi devices go further, flagging suspicious calls with a warning before you even pick up.
But native phone settings are just the first line of defense. The federal government maintains a service called Não Me Perturbe—regulated by ANATEL, Brazil's telecommunications authority—that works like a legal cease-and-desist order. When you register, you're formally prohibiting telecom companies and their partners from contacting you to sell anything without your explicit permission. Registration is free and takes minutes through the website or app. A significant shift happened in September 2025: ANATEL made compliance mandatory for every telecom provider in Brazil, including smaller ones. This dramatically expanded the service's reach and reinforced a consumer's right to be left alone. There are exceptions—debt collection calls, fraud prevention, data confirmation, and portability retention still get through—but unsolicited sales pitches do not.
Consignado loans deserve special attention because they're relentless, especially targeting retirees, pensioners, and civil servants. The INSS—Brazil's social security agency—offers a direct blocking mechanism. You can activate it through the Meu INSS app by navigating to Loan Blocking, or call 135 for free and request it over the phone. The process is immediate. Most banks also allow you to block loan offers directly in their apps under privacy or contact preferences. If you want to see what's already active on your CPF, the Central Bank's Registrato system shows every consignado credit contract linked to your name, making it easy to spot unauthorized agreements.
When blocking measures fail—and sometimes they do—the Consumer Protection Code is on your side. Persistent, unauthorized contact qualifies as abusive practice under Brazilian law, which opens the door to complaints at PROCON or small claims court. The key is documentation: save the calling number, date, and time of each unwanted call. This record becomes evidence of a pattern, making it far easier for authorities to act.
For those wanting an extra layer, apps like Whoscall, Truecaller, and Google's call identifier for Android cross-reference incoming numbers against spam databases in real time, alerting you before you decide whether to answer. These apps learn from user reports and grow more accurate over time. Stacked together—native phone filters, Não Me Perturbe registration, INSS blocking, and a third-party identifier app—they create a solid barrier against the daily interruptions.
The point is simple: you don't have to accept this. The tools exist. Some are built into your phone. Others are free government services. The control over who reaches you should be yours, and now it can be.

The Hearth Conversation Another angle on the story
Why does this matter so much right now? People have been getting unwanted calls for years.
Because in September 2025, ANATEL made something that was voluntary suddenly mandatory. Every telecom provider in Brazil—even the tiny ones—now has to respect the Não Me Perturbe registry. That's enforcement with teeth.
But people still get calls after registering, don't they?
They do, which is why the story isn't just about one tool. It's about layering them. Your phone's native filter, the government service, the INSS block, maybe an app. Each one catches what the others miss.
What about the consignado loans specifically? Why are those singled out?
Because they're weaponized. Retirees and pensioners get hammered with offers. The INSS block is direct—it stops banks from even offering the product. It's the closest thing to making the calls stop at the source.
What happens if someone ignores all of this and keeps calling?
Then you have legal recourse. It becomes documented harassment under consumer law. You file with PROCON or go to small claims court. But you need the evidence—dates, times, numbers. That's why documentation matters.
So this is really about giving people back control?
Exactly. For years, the default was that companies could reach you unless you fought back. Now the default can be the opposite—they can't reach you unless you let them.
