How to unblock a phone number depends on whether you are using an iPhone or Android device, since each platform stores blocked contacts in a different place. The process is usually quick, but settings such as spam filters, Focus, or third-party calling apps can still prevent calls or messages from coming through afterward.
The good news is that unblocking is reversible and does not notify the other person. Read on to find the current steps for iPhone and Android, what changes after you unblock someone, and which settings to check if the number still seems blocked.
1. What You Need Before You Start
You do not need any special tools or technical skills to unblock a number, but a few quick checks can make the process easier.
First, make sure you have access to the phone where the number was originally blocked. If you use more than one calling or messaging app, remember that a contact may be blocked in one app but not another.
It also helps to know where the block was created. On iPhone, blocked contacts are managed through the system settings, while Android phones may keep blocked numbers inside the Phone app, Messages app, or another calling service depending on the manufacturer.
Before you begin, check the following:
- Make sure you know the number or contact you want to unblock.
- Confirm whether the block was created in the Phone app, Messages, FaceTime, or a third-party app.
- Check whether spam filtering or unknown-caller settings are also active.
- If you use dual SIM or multiple phone apps, confirm which line or app is receiving the calls.
- Keep your phone updated so the settings menus match the latest available options.
These checks help you avoid unblocking the number in one place while another setting continues to silence or filter the contact.
2. How to Unblock a Phone Number on iPhone
To unblock a number on iPhone, open the Settings app and go to the Blocked Contacts list.
On current iOS versions, Apple places this under Settings > Privacy & Security > Blocked Contacts, where you can review and remove blocked contacts.
- Open Settings
- Tap Privacy & Security
- Tap Blocked Contacts
- Tap Edit
- Tap the remove button next to the number or contact
- Tap Unblock
On some iOS versions, you may also find the list under Settings > Apps > Phone > Blocked Contacts.
Alternative method from Messages:
You may also be able to unblock a contact from its contact or conversation details, depending on your iOS version. If that option is not available, use the Blocked Contacts list in Settings.
Note: Unblocking does not send a notification to the other person, and it does not restore any calls, texts, or voicemails from the period they were blocked.
3. How to Unblock a Phone Number on Android
On Android, blocked numbers are managed inside the Phone app’s settings menu. The exact wording can vary slightly by manufacturer, but the steps below work on most devices.
- Open the Phone app
- Tap the three dots in the top-right corner
- Tap Settings
- Select Blocked numbers (some devices show Block numbers or Call settings)
- Find the number you want to unblock
- Tap the X or minus (−) icon next to it
- Confirm Unblock
Device variations:
- Samsung: Phone app > three dots > Settings > Block numbers
- Google Pixel: Phone app > three dots > Settings > Blocked numbers
The exact menu names vary by manufacturer and Phone app, but many Android devices keep blocked numbers somewhere inside the Phone app’s settings.

4. What Happens After You Unblock a Number?
Once you carry out how to unblock a phone number, that contact can immediately call, text, and (on iPhone) FaceTime you again.
However, unblocking does not retroactively deliver blocked calls or messages. Voicemail behavior can vary by device and carrier, so check your voicemail separately if needed.
No notification is sent to the unblocked contact. They will not know when you unblock them.
If the number was blocked in both Phone and Messages settings on some Android devices, you may need to unblock it in each app separately. Going forward, all new calls and texts from that number will come through normally.
5. If the Number Is Still Being Blocked
If calls or texts still aren’t coming through after you’ve unblocked a number, a few other settings could be interfering.
- Check other messaging or calling apps. If you use a third-party app for calls or texts, the number may be blocked there separately
- Review spam filtering and carrier blocking. Some carriers offer their own spam-blocking features that operate outside your phone’s built-in block list
- Check Focus, Do Not Disturb, and unknown-caller filtering: These settings can silence or filter calls even when the number is not blocked. Review which people or caller types are currently allowed through.
- Restart the phone if calls or messages still do not come through, since a restart can clear temporary app or system glitches.
- Confirm you’re using the correct Phone app. If your device has more than one calling or messaging app installed, double-check that you unblocked the number in the one you actually use

6. Frequently Asked Questions
Q1. Does unblocking a number notify the other person?
No. Neither iPhone nor Android sends a notification when you unblock a contact. They will not know unless they try calling or texting and it goes through.
Q2. Will I get the messages that were sent while a number was blocked?
No. Blocked calls and messages are generally not delivered retroactively after you unblock the number. Voicemail behavior can vary by phone and carrier, so check your voicemail separately.
Q3. Why can’t I find the Blocked Contacts option on my phone?
On current iPhones, go to Settings > Privacy & Security > Blocked Contacts. On Android, the option is usually inside the Phone app’s settings, although the exact label varies by manufacturer and app.
Conclusion
Unblocking a contact is simple once you know where your phone keeps its blocked-number list. On current iPhones, the setting is under Privacy & Security, while Android phones usually manage blocked numbers inside the Phone app.
Knowing how to unblock a phone number is also useful when calls still do not come through after the change. In that case, check spam filters, Focus or Do Not Disturb settings, and any third-party calling or messaging apps that may still be limiting the contact.
