how to block a phone number

If you’ve ever received an unwanted or suspicious phone call, you are likely doing research to learn how to block a phone number.

Effectively blocking a phone number can be difficult, as there are many ways around some of the most well-known solutions to stopping unwanted calls.

In this post, you will learn:

Learning how to block a phone number is important for these reasons.

If you’ve ever been a victim of phone harassment or phone fraud, you know the importance of always knowing who is calling. Learning how to block phone numbers effectively is extremely important to protect yourself from the dangers and interruptions of phone scams and phone harassment.

Here are 3 major reasons why blocking unwanted phone numbers are important:

  1. You take control over who is able to contact you over the phone
  2. You don’t have to change your phone number (or throw it out a window)
  3. You protect yourself, your money, your identity, and your time

How to block a phone number on iPhone

While it is true that Apple offers basic phone number blocking by default, but the unfortunate reality is it’s fairly ineffective to block most forms of unwanted calls.

A well-known hack to block unwanted spam and robocalls on your iPhone is to block individual phone numbers after you’ve received a suspicious or unwanted call. Users are directed to do the following:

  1. Go to “Settings”
  2. Open “Phone”
  3. Select “Call Blocking & Identification”
  4. Select “Block Contact”
  5. Enter the phone number or select an existing contact

Can you guess why the above solution may be ineffective? First, if you’re experiencing issues with a blocked caller, there is an easy solution to override Apple’s default blocking functionality. If someone still wanted to call you, all they would have to do is call you blocked by dialing *67 before your phone number and voila! They can reach your phone and voicemail.

This solution also poses a challenge if you are trying to stop spam calls. Caller ID spoofing, the technology that allows you to place a call from a caller ID that is not truly your own, makes it easy for phone spammers (especially those looking to steal from you) to call you from a fake number.

Each time they call, it is a unique phone number that you likely do not have on your block list. So, no matter how many times you try to add these phone numbers to your block list, spammers will still be able to reach your phone.

How to block a phone number on Android

Android also offers default call blocking to block unwanted phone numbers from reaching you, but much like the iPhone, is no match for the complexity of blocking most unwanted calls.

The most well-known solution to block a phone number on Android phones is as follows:

  1. Open the “Phone” app
  2. Tap on “Settings”
  3. Tap Settings for “adding and removing blocked numbers”
  4. Turn on “Block Unknown Callers”


The same issues with the above solution hold true for Android as they do for iPhone. If you block someone’s phone number, it is easy for them to override that by calling you from a blocked phone number. If you try to block a spam call, you’re only blocking the fake phone number – not the spammer themselves! Both types of unwanted calls will continue to persist if you follow the above steps on Android.

Call blocker apps are the most effective solution to block a phone number

How to Text Your Ex, Even If They’ve Blocked You

The good news is that there is only good news. There is an easy way to text your ex if they have blocked your phone number.

Because your phone number has been blocked and your ex likely will recognize your phone number, caller ID spoofing is the most effective way to get past default iPhone and Android phone number blocking.

Caller ID spoofing allows you to change your caller ID to send and receive texts and calls from any phone number of your choosing. You can change your caller ID to a number similar to your ex’s, change your caller ID to show as blocked, or even display the number of his/her new partner, if you know who that is. 

SpoofCard is the best app to easily send calls and texts from a spoofed phone number. With SpoofCard, your caller ID no longer holds you back from getting your point across – especially after a bad breakup.

Follow these simple steps to text your ex if they’ve blocked your phone number:

  1. Open the SpoofCard App
  2. Select “SpoofText” on the navigation bar
  3. Select “New SpoofText”
  4. Enter the phone number to send the text to, or select from your contacts
  5. Select the phone number you’d like to display as your caller ID

It’s really that simple! From there, SpoofCard will allow you to send and receive text messages in the “Spoof Texting” feature within the app.

Your text messages are delivered to your ex’s phone, and even if they try to block that caller ID you will be able to easily send a text from a new phone number within seconds.

Best of all, if they reply, you will see their response and be able to continue the dialogue. Who knows, maybe things will work out for the better after you contact them!
