How to block spam calls
Spam calls can be annoying and disrupt our daily lives. We receive calls from unknown or even international numbers trying to sell products, services, or scam us. This type of call can be very stressful and invasive.
However, there are several solutions to block spam calls and protect your privacy. In this article, we will show you how you can defend yourself against unwanted calls using some simple strategies.
How do spam calls work?
Spam calls are made by automated telemarketing or people trying to sell products or services. Often, these calls are made randomly without any specific reason.
Automated telemarketing uses software that automatically dials a list of phone numbers and plays a prerecorded message. In some cases, messages may also be customized based on the recipient's geographic location.
The people making these calls may also use deceptive techniques to convince the recipient to purchase a product or service. For example, they may pretend to represent a well-known company in order to obtain personal or financial information from the recipient.
- Note: In some cases, spam calls can also be dangerous. For example, they may try to install malware on your device or make you pay for services you did not request.
To protect yourself from spam calls, you need to take some precautions and use some effective strategies. Keep reading to find out how.
Identifying spam calls
Before you can block spam calls, it is important to be able to identify them. Here are some signals that may indicate an unwanted call:
- The number is not saved in your contacts
- The call comes from an unknown or foreign area code
- The person on the other end of the line offers you services or products you did not request
- The call comes at unusual times or repeatedly during the day
In addition, if you receive a call and hear a recording instead of a person speaking, it is likely a spam call. These recordings are often used to advertise products or services.
Remember that some legitimate organizations, such as banks or credit card companies, may contact you by phone. However, these calls should be confirmed through other channels before providing personal or financial information.
Blocking spam calls on iPhone
If you are an iPhone user, you have several options to block spam calls. Here's how:
1. Use the "Silence Unknown Callers" feature
This feature allows you to silence all calls from numbers not saved in your contacts. This way, if you receive a call from an unknown number, your iPhone will not make any sound and won't disturb you.
To activate this function, go to Settings > Phone > Silence Unknown Callers and turn on the switch.
2. Add unwanted numbers to the blocked contacts list
To block specific numbers that are bothering you with spam calls, you can add them to the blocked contacts list. This way, when one of these numbers calls you, the call will be immediately rejected.
To add a number to the blocked contacts list, open the Phone app, select the number you want to block, and tap "Block this Caller".
3. Use a third-party app
There are several apps available on the App Store that can help you block spam calls more effectively. For example, Truecaller is a free app that uses a database of unwanted numbers to automatically block spam calls.
To install Truecaller, open the App Store, search for "Truecaller", and tap "Install". After installing the app, follow the instructions to activate the spam call blocking feature.
- Remember that some third-party apps may require access to your contacts and personal information. Be sure to read the terms and conditions carefully before installing any app.
In summary, if you want to block spam calls on iPhone, you can use the "Silence Unknown Callers" function, add unwanted numbers to the blocked contacts list or use a third-party app like Truecaller. Choose the solution that best suits your needs and don't let spam calls bother you anymore!
Blocking Spam Calls on Android
Spam calls are becoming increasingly common and annoying. Fortunately, there are several options available to block them on Android devices.
1. Use a call blocking app
There are numerous call blocking apps available on the Google Play Store that can help you filter unwanted calls. Some of the most popular apps include Truecaller, Mr. Number, and Call Blocker.
After downloading the app, follow the instructions to set it up according to your preferences. Most apps will allow you to block specific numbers or unknown numbers.
2. Add the number to the blocked contacts list
Another option is to manually add unwanted numbers to your Android device's blocked contacts list. To do this, open the Contacts app and search for the number you want to block. Tap on the number and select "Block this number" or "Add to blocked contacts list". This will prevent the number from calling you in the future.
3. Configure anti-spam filter settings
Some Android devices offer a built-in anti-spam filter feature that you can activate in your phone's settings. To do so, go to Settings > Calls > Anti-spam filter. Here you can choose to block calls from unknown numbers, private numbers, or specific numbers.
4. Use your phone operator's call blocking service
Finally, many phone operators offer a call blocking service for their customers. Contact your operator and ask for information on how to activate this service.
- Remember that some call blocking apps can cause problems with receiving legitimate calls. Be sure to test the app before using it regularly.
- Additionally, if you frequently receive spam calls from different numbers, it may be helpful to change your phone number or use a temporary number to avoid further annoyance.
Blocking spam calls on Android requires only a few simple but effective steps. Choose the option that best suits your needs and enjoy greater peace of mind during your days.
