If you're tired of receiving unwanted calls and texts from certain numbers, this guide will explain how to block them on your cell phone. We'll also explore the pros and cons of blocking, as well as alternative strategies to manage unwanted contacts.


Have you ever received a phone call or text message from someone you don’t want to talk to? Perhaps it’s a telemarketer, or an ex who won’t leave you alone. Whatever the reason, unwanted calls and texts can be annoying, or even potentially dangerous in some cases. Thankfully, most cell phones offer a way to block certain numbers from contacting you. In this article, we’ll show you how to block a cell phone number, step-by-step.

Step-by-Step Guide

The process for blocking a number on your cell phone will vary depending on your device and operating system. However, the following steps should work for most smartphones:

  1. Open the Phone app on your mobile device.
  2. Find the call log or contacts list, and select the number you want to block.
  3. Tap the information icon (usually an “i” with a circle around it) next to the number.
  4. Select the option to “block this number.”
  5. Confirm that you want to block the number, then exit the menu.

If these steps don’t work for you, consult your phone’s instruction manual or search online for specific instructions. Additionally, some phones may require you to contact your carrier to block a number.

It’s important to note that while blocking a number can prevent them from calling or texting you, it may not necessarily stop them from leaving voicemails. Some smartphones also include an option to block voicemails as well, so be sure to check your phone’s settings or consult your manual for more information.

Pros and Cons of Blocking Numbers

While blocking a number can be an effective way to prevent nuisance calls and texts, there are also some drawbacks to consider. Here are some of the pros and cons of blocking numbers on your cell phone:


  • Peace of mind knowing that unwanted contacts can’t reach you
  • Alleviates anxiety caused by persistent or harassing callers
  • Protects your privacy and personal information


  • The blocked number may be notified that they’ve been blocked
  • You may miss important calls or messages if you accidentally block a number that you need to hear from
  • Blocking doesn’t necessarily stop other numbers from calling or texting you

It’s important to weigh these pros and cons carefully before deciding to block a number on your phone.

Using Third-Party Apps

In addition to the built-in blocking features on most smartphones, there are also third-party apps you can download to provide additional options and filtering capabilities. Some popular apps for blocking unwanted calls and texts include:

These apps can be useful if you want more granular control over who can reach you, or if you want to block calls or texts from entire categories of numbers (such as telemarketers, political campaigns, or debt collectors.)

However, it’s important to note that third-party apps may not be as effective at blocking certain types of numbers (such as “spoofed” or fake phone numbers that change frequently.) Additionally, some apps may come with their own privacy concerns or unwanted ads.

Alternatives to Blocking

If blocking a number isn’t the best option for your needs, there are other strategies you can use to manage unwanted calls and texts. Some of these strategies include:

  • Using caller ID to screen incoming calls or texts
  • Changing your phone number (although this can be a hassle and may not always solve the problem)
  • Reporting persistent or harassing callers to your phone carrier or law enforcement
  • Filing a complaint with the Federal Trade Commission’s (FTC) National Do Not Call Registry

Be sure to evaluate each of these strategies carefully to determine which ones may work best for your individual situation.


Blocking a cell phone number can be an effective way to prevent unwanted calls and texts from reaching your phone. However, it’s important to weigh the pros and cons carefully and explore other strategies for managing unwanted contacts if blocking isn’t the best option for your needs. By taking control of your cell phone’s privacy and security, you can enjoy a safer and more stress-free mobile experience.
