Blocking a number on your child’s iPhone is one of the most effective ways to reduce spam, prank calls, or contacts you don’t want them interacting with. Learning how to block a number on iPhone not only shuts out unwanted callers but also gives you peace of mind as a parent or guardian. In this guide, you’ll find five practical methods—from native iOS features to third-party tools like mSpy—that help you manage incoming calls and maintain privacy.
Use built-in block feature
The simplest way to block a number is with Apple’s native block option. Once you block a caller, they can’t reach your child via phone calls, Messages, or FaceTime.
Block from recents
- Open the Phone app on your child’s iPhone.
- Tap Recents at the bottom.
- Find the unwanted number and tap the info (i) icon.
- Scroll down, then tap Block this Caller.
Block from contacts
If the number is already saved in Contacts:
- Open Contacts and select the entry.
- Scroll to the bottom and tap Block this Caller.
These steps instantly prevent that number from contacting your child again across voice, text, and FaceTime.
Use Screen Time restrictions
Screen Time offers granular communication limits that apply to phone calls, Messages, and FaceTime. You can enforce these rules remotely if you’ve set up Family Sharing.
• In Settings, tap Screen Time > [Child’s Name].
• Select Communication Limits.
• Under During Allowed Screen Time, choose Contacts Only or Specific Contacts.
• Under During Downtime, repeat the selection.
By restricting calls to known contacts, you ensure only approved numbers can reach the device. This method is ideal if you want a blanket approach rather than blocking each number one by one.
Enable Focus mode
Focus mode filters notifications and calls based on criteria you set. A custom Focus works like Do Not Disturb but with more options for allowed callers.
- Go to Settings > Focus and tap the + icon.
- Choose Custom or select Do Not Disturb.
- Under People, tap Calls From and select Contacts Only.
- Optionally add exceptions for urgent contacts or groups.
When this Focus is active, calls from unknown or blocked numbers won’t ring or notify. You can enable it on a schedule (for example, at bedtime) or activate it remotely via Family Sharing.
Silence unknown callers
If you don’t want calls from numbers not in your child’s contacts, Silence Unknown Callers sends them straight to voicemail without ringing.
• Open Settings > Phone.
• Toggle on Silence Unknown Callers.
This method is perfect for blocking robocalls and numbers you’ve never saved. Keep in mind any urgent call from an unknown number will also be silenced, so review voicemails regularly.
Install mSpy monitoring app
For parents who want advanced blocking, monitoring, and reporting features, mSpy is one of the best apps available. It not only lets you block numbers remotely but also tracks call logs, messages, and social media activity.
To set up mSpy:
First, sign up for a plan on the mSpy website and follow the on-screen instructions to install the app on the child’s iPhone. Once installation is complete, open your mSpy dashboard in a browser. Under the Calls section you can:
- View incoming and outgoing call logs in real time
- Block specific numbers or entire area codes
- Create watchlists to flag repeat callers
mSpy also offers geofencing, message recovery, and social feed monitoring. Its remote configuration means you don’t need to physically handle the device each time you want to update settings.
