The simple trick to stop telemarketers for good.

Telemarketing calls have become an everyday hassle. At any time of the day, the phone rings and, when you answer, an unknown voice tries to sell you a service, insurance or a promotion. While many countries have created “Do Not Call” lists to protect users, the reality is that these measures are not always effective, and contact numbers are often leaked in one way or another.

The interesting thing is that there is a simple trick that promises to nip this problem in the bud: dial the number 9 during the call.

How does this trick work?

When you receive a telemarketing call, the management systems that companies use are usually programmed to interpret certain numbers as commands. Pressing 9 during the call sends an automatic signal that tells the system to remove your number from the contact list.

In theory, this generates two immediate effects:

• The call is dropped instantly, preventing the conversation from continuing.
• Your number is recorded as “unavailable” or “not interested”, so it is removed from future attempts.

Is it an infallible method?

Although the idea is attractive and has circulated widely on the internet, it is important to clarify that it does not always work in all cases.

• Some call centers use advanced systems that do not interpret these types of commands.
• In others, the number 9 simply hangs up the call without generating an actual record.
• In addition, there are companies that constantly change numbers to evade blocks.

So, while it’s worth a try, it shouldn’t be the only strategy to protect your peace of mind.

Additional alternatives and methods for blocking calls

To complement this trick, there are other ways to defend yourself from unwanted calls:

1. Registration on official “Do Not Call” lists

In many countries there is a database where you can register your number to prevent companies from contacting you. Although it is not perfect, it usually significantly reduces the frequency of calls.

2. Call Blocking Apps

Tools like Truecaller or native iOS and Android blockers identify suspicious calls and allow you to filter them automatically.

3. Manual lock from your phone

Almost all current mobile phones allow you to block numbers individually. If you receive repeated calls from the same number, simply add it to your blacklist.

4. Contact your phone company

Some carriers offer additional services to block spam calls or restrict certain types of contact.

5. Be wary of suspicious surveys

Data is often obtained through “surveys” or online forms. Avoid sharing your number on untrustworthy sites.

Final tips to protect yourself

1. Never share personal data on a telemarketing call, unless you are absolutely sure of the company’s identity.
2. Don’t return calls to unknown numbers, as some could be traps to charge you international rates.
3. Keep your phone and apps up to date for the latest security and locking features.
4. Be persistent: combining the number 9 trick with the other tools can give you the peace you need.

This way, you’ll have a comprehensive strategy to keep your phone free of telemarketing calls and regain your peace of mind!
