Why Blocked Numbers are Still Coming Calls 2024

Still Blocked Calls are Coming? Tips for Android & IOS Number Blocks

Why Blocked Numbers are Still Coming Calls, Unwanted calls from unfamiliar numbers and telemarketers can disrupt your productivity during work hours. Fortunately, both Android and iPhone devices offer features to block such nuisance calls. Nevertheless, some users have reported continued calls from blocked numbers. This article delves into the reasons behind receiving calls from blocked numbers and provides troubleshooting steps to address the issue.

Dealing with calls from blocked numbers can be frustrating, particularly when you’re in a meeting or handling crucial tasks. Instead of resorting to the extremes of enabling Do Not Disturb (DND), silent mode, or turning off your phone entirely, follow the steps outlined below to effectively prevent interruptions on your device.

How Blocked Calls Manage to Get Through

Blocking specific phone numbers is a common practice, yet there are instances where blocked calls still find a way to your device. Particularly, when it comes to voicemail messages, the dynamics of call blocking may not entirely halt the calls from the caller’s end.

Blocking calls through your phone settings prevents the calls from ringing on your device, rerouting them to voicemail after a brief ring. However, it’s important to note that this approach addresses the issue on your end, not the caller’s.

Although phones offer call-blocking features, the calls may still be received if blocked through device settings. For comprehensive blocking, especially preventing calls from even reaching your number, it is advisable to utilize your network or phone service provider. Mobile companies are adept at handling spam and harassment calls, making it more effective to block numbers through their services.

While your iPhone or Android device can block calls, it may not completely prevent voicemails and notifications, emphasizing the need for a holistic approach to call blocking.

Reasons Behind Persistent Calls from a Blocked Number

Wondering why a blocked number is still managing to reach you with calls? Several factors could contribute to this persistent issue:

  1. Ineffective Blocking: The blocking feature on your device might be experiencing glitches or inefficiencies, potentially due to software issues.
  2. Different Blocking Methods: Blocking a number from your call log may not necessarily prevent them from reaching your voicemail or sending text messages. The effectiveness of blocking can vary based on the phone model and Android version.
  3. App Override: Third-party apps designed for calls or messages might override your phone’s default blocking mechanism, allowing blocked numbers to bypass restrictions.
  4. Carrier-Based Blocking: Certain mobile carriers provide their own blocking services. If you have exclusively blocked a number on your device and not through your carrier’s service, the blocked caller may still manage to bypass the restrictions.
  5. Changing Numbers: Persistent callers may resort to using different phone numbers or VoIP services to circumvent number-based blocks.
  6. Hidden or Private Numbers: Calls from hidden or private numbers might not be recognized by your phone as the blocked number, even if it’s from the same individual you intended to block.

Reasons You’re Still Receiving Texts from a Blocked Number

Continuing to Receive Texts from a Blocked Number? Here’s What You Need to Check

If you find yourself still getting texts from a blocked number, it’s essential to confirm that you’ve effectively blocked them across all relevant apps on your phone.

For iPhone users, this involves blocking the number in various apps such as Phone, FaceTime, Messages, and Mail. Navigate to Settings, select the respective app, access Blocked Contacts, and verify that the number is listed.

Android users can achieve this directly within the Messages app. Locate the conversation with the number you wish to block, press and hold the message, then choose the option to block. Ensure you’ve covered all the bases to prevent unwanted texts.

Effective Measures to Tackle Unwanted Calls

  1. Verify Block Settings: Navigate to your phone settings and confirm that the number is genuinely blocked. Keep in mind that the location of this setting may vary depending on the phone manufacturer and Android version.
  2. Explore Third-Party Apps: Explore the use of third-party apps such as Truecaller or Hiya, equipped with advanced blocking and spam detection features. These apps can efficiently identify and block suspicious calls.
  3. Seek Carrier Assistance: Reach out to your service provider for assistance. Some carriers offer enhanced blocking features, providing an additional layer of protection against unwanted calls.
  4. Activate Do Not Disturb: As a final resort for persistent unwanted calls, activate the “Do Not Disturb” mode on your phone. This setting allows calls only from your contacts or favorites, silencing other calls while still logging them.
  5. Report Incidents: If you feel harassed, consider reporting the issue to local authorities. Continuous unwanted calls can be a form of harassment, and legal actions may act as a deterrent.
  6. Keep Software Updated: Ensure your phone’s software is up-to-date. Software updates can sometimes improve blocking features or address bugs associated with them.

Remember, while blocking is a useful tool, determined individuals may attempt to circumvent it. Exercise caution in sharing your number and contemplate changing it if harassment reaches an intolerable level.

Telemarketers Exploiting Similar Number Series

In the ongoing battle against unwanted calls, telemarketers and advertisers have developed clever strategies to bypass blocking mechanisms. Recognizing that people often block specific numbers, these entities employ a tactic of utilizing similar numbers within the same series. For instance, if you block a number like 9946328450, telemarketers may resort to using variations like 9946328451 and other similar sequences to circumvent your blocked list.

To effectively ward off calls from advertisers, it becomes essential to proactively block each distinct number within these series on your phone.

Can You Block No Caller ID Calls on Android/iOS?

Why Blocked Numbers are Still Coming Calls

Frequent calls from unknown caller IDs can be a source of frustration, especially when you can’t identify the specific number to block them individually.

Unfortunately, it’s impossible to block these calls individually, as the other person’s number remains unknown. However, you can take a proactive approach by blocking all unknown numbers, particularly if you’re facing harassment.

On an iPhone:

  1. Navigate to Settings.
  2. Select Phone.
  3. Scroll down and tap “Silence Unknown Callers.”

On an Android device:

  1. Open the Phone app.
  2. Select More.
  3. Tap Settings.
  4. Click “Blocked numbers” and turn off “Unknown.”

While this won’t allow you to block unknown numbers individually, it effectively prevents all calls from unknown or hidden numbers, serving as a helpful measure against spam or unwanted calls.

Pro Tip: Muting Calls from Unknown Numbers

If you’d rather avoid the constant task of individually blocking unknown callers, consider silencing them on both iPhone, Android, and third-party apps like WhatsApp.


  1. Navigate to Phone Settings (refer to the provided steps).
  2. Select “Blocked numbers” and activate the Unknown toggle.


  1. Open the Settings app and access the Phone menu.
  2. Scroll to “Silence Unknown numbers” and toggle the option.


  1. Open WhatsApp and go to Settings.
  2. Select Privacy.
  3. Tap on Calls and enable the “Silence unknown callers” toggle.

By implementing these settings, you can significantly reduce interruptions from unknown numbers on your device. Additionally, for those using FaceTime, be aware that some blocked numbers may still attempt to reach you. In such cases, ensure you block their Apple ID to fully prevent calls.

Avoid Third-Party Apps for Blocking Numbers

Why Blocked Numbers are Still Coming Calls

If you rely on third-party applications like Truecaller to block unwanted numbers on your phone, be aware of potential issues that may arise. The Android system has a tendency to put such apps to sleep when they go unused for an extended period. This dormancy can disrupt the functionality of blocked filters, leading to the reception of calls from previously blocked numbers.

Moreover, accidental uninstallation of the app, whether by you or someone else, results in the unblocking of all previously blocked numbers, leaving you vulnerable to unwanted calls.

To prevent these issues, consider taking the following steps:

Locking the App:

  1. Open the recent apps menu on your Android device.
  2. Tap on the app icon.
  3. Select “Lock” to ensure the app remains active and effective.

Granting Unrestricted Battery Usage:

  1. Long-press on the app icon to open the app info menu.
  2. Choose “App battery usage.”
  3. Tap the radio button next to “Unrestricted” to allow the app unrestricted battery usage.

While third-party apps can be helpful in blocking calls, it is advisable to exercise caution and, whenever possible, rely on the default Phone app to mitigate potential complications.

Limitations of Default Phone App Filters

The built-in filters in default phone apps on Android and iPhone devices, designed to screen out spam calls, may not always perform as expected. In certain situations, these filters might fail, allowing calls from unknown numbers to reach your phone. To enhance your control over incoming calls, it is advisable to take a proactive approach by individually blocking troublesome contacts rather than relying solely on these filters.

Blocking Numbers on Third-Party Messaging Apps

When you block unknown callers on your iPhone or Android device, it effectively prevents them from reaching you through regular calls or messages. For a detailed understanding of the implications of blocking someone on your iPhone, you can refer to our dedicated guide.

However, it’s crucial to note that such blocked callers can still potentially contact you through third-party messaging apps such as WhatsApp and Telegram. To ensure comprehensive blocking, it’s necessary to take proactive measures and block these contacts within the specific messaging platforms as well.


Occasionally, even after blocking a phone number, you may still encounter calls from that particular contact. While this is uncommon, it can be a source of inconvenience.

If you continue to receive video calls or phone calls from a blocked number, it suggests that the blocking feature is not as effective as desired. In such instances, following the outlined steps above should enhance the security of your phone and prevent these numbers from reaching you in the future. By taking proactive measures, you can ensure a more robust defense against unwanted calls.
