How to block a number on an iPhone
Likely the most convenient method: In your Phone app, go into your recent calls and tap the icon that looks like an “i” inside a circle next to the call from the number you’re looking to block. On the next screen, select “Block this Caller.”
Once you’ve blocked someone, you won’t receive further communication from that number via Apple’s communication apps; calls, texts, and FaceTime requests will be blocked. (They can still leave a voicemail, but it will be hidden from your view.)
However, the blocked number could still contact you through third-party apps.
Also, any blocked person won’t be notified of the block. That said, there are ways to check if you’ve been blocked on an iPhone, though they aren’t definitive.
Quick tip: You can view your blocked iPhone contacts on several different app screens.
If you want to unblock a number on your iPhone, go into your recent call list on your Phone app, find the person or number you want, tap the “i” icon next to the name or number, and on the next screen tap “Unblock this Caller.”
How to block a number on Android
To block a number on an Android, go into the Phone app and tap the three dots in the top-right corner, select “Settings,” then tap “Blocked numbers” and add a number to the list.
Or, you can block numbers via the messages app, though the exact process will depend on your device. Either way, they won’t be notified and they won’t know for sure that you’ve blocked them, even if they try to find out if they’ve been blocked.
Variance is pretty common among Android devices, and blocking private or unknown numbers is another instance where the process may vary depending on your device. For example, if you have a Samsung Galaxy S10, you can block all of those unknown calls via the settings in your Phone app.
Note: When you block a number on a Galaxy S10, you won’t get calls or texts from them anymore, but you retain the option to call or text them.
If that isn’t setting isn’t an option for your device, though, you can still block those calls on a case-by-case basis, using the three-dot method listed above.
If you want to unblock a number on Android, you can do so via the blocked numbers list in your Phone app.
