What Happens When You Block Someone on Android or iPhone

When you block a number on your iPhone, you won’t receive regular voice calls, FaceTime calls, or messages from them. However, you can still call or message the blocked person. In certain countries, the blocked person can still leave a voicemail, but you won’t receive a notification.

On Android, if a blocked person tries to call you, it will be declined automatically, and their messages won’t be delivered to you.

It is essential to remember that the blocked individual may still contact you via other applications, such as WhatsApp, Telegram, Facebook, and so on, as the block on these platforms is separate from the phone’s block.

How to Block Unknown Callers on Android

On Android, you can block calls from private or unidentified numbers using a native setting in the phone app. Please note that this setting will not block spam calls or numbers that aren’t saved in your contacts. It will only affect unknown callers.

1. On your Android phone, open the Phone app.
2. Tap on the three-dot icon and go to “Settings.”

3. Tap on “Blocked numbers.”
4. Enable the toggle next to “Unknown.”

How to Block Unknown Callers on iPhone

Unlike Android, you can use the “Silence unknown callers” feature to silence calls from numbers that aren’t in your contacts list. However, this feature will not silence numbers you have previously interacted with or numbers shared with you via email. Furthermore, if you make an emergency call, the feature will be disabled for 24 hours.

Please keep in mind that this feature does not completely block calls. The calls are simply silenced and routed to voicemail. They will continue to appear in your recent calls list.

1. On your iPhone, open the Settings app and go to “Phone.”

2. Scroll down and tap on “Silence Unknown callers.”

3. Enable the toggle next to “Silence unknown callers” on the resulting screen.
