Block a number directly from a call or text

The fastest way to block a number on an LG phone is to do it the moment you see the call or message. When a call comes in from a number you want to block, press the red decline button, then look for a "Block" or "Block number" option that appears on your screen. On most LG models, this option shows up when ready after you decline.

If you're blocking from a text message instead, open the message thread, press and hold the sender's number or name, and select "Block" from the menu that appears. The exact wording varies slightly between LG models and Android versions, but the option will be clearly labeled.

Once you block a number this way, that caller won't be able to reach you by phone or text. Their calls go straight to voicemail without ringing your phone, and their text messages won't appear in your message threads.

Key Takeaways

  • You can block a number when ready when a call or text arrives by declining and selecting the block option from the menu.
  • The Phone app's contact list and call history both let you block numbers retroactively, even if you didn't block them when they first called.
  • Blocked callers can still leave voicemails, but you won't see notifications for them unless you check your voicemail folder manually.
  • You can unblock a number at any time by finding it in your blocked list and selecting unblock.

Block a number from your call history

If you didn't block a number when it called, you can still block it later from your call history. Open the Phone app on your LG, tap the "Recents" or "Call History" tab at the bottom, and find the number you want to block. Press and hold that entry until a menu appears.

Select "Block number" or "Block contact" from the menu. Some LG models may label this as "Add to block list" or show it under additional options (often marked with three dots). The number is now blocked and won't be able to call or text you.

This method works even for numbers that called you days or weeks ago. As long as the call appears in your history, you can block it retroactively.

Block a number from your contacts

If the number is already saved in your contacts, you can block it from there. Open your Contacts app, find the person's name, and tap to open their contact card. Look for a menu button (usually three vertical dots in the top right corner) and tap it.

Select "Block contact" or "Block number" from the menu. The contact remains in your phone, but they can no longer reach you by phone or text. If you ever want to unblock them, you return to their contact card and select "Unblock."

View and manage your blocked list

To see all the numbers you've blocked, open the Phone app and look for a menu button or settings option. On most LG phones, this is three horizontal lines (called a hamburger menu) or three dots in the top corner. Tap it and look for "Blocked numbers," "Block list," or "Settings."

Once you're in the blocked list, you can see every number you've blocked. If you want to unblock someone, find their number in the list, tap it, and select "Unblock." They'll when ready be able to call and text you again.

Some LG models also let you block numbers directly from this screen by tapping a plus button and typing in the number manually. This is useful if you want to block a number before they ever call you.

What happens when you block a number

When you block a number on your LG phone, that person cannot call you, and their calls won't ring through or show up in your call history. Text messages from blocked numbers also won't appear in your message threads. You won't receive notifications when a blocked caller tries to reach you.

Blocked callers can still leave voicemails, but you won't get a notification about them. If you check your voicemail folder manually, you may see messages from blocked numbers, depending on your voicemail settings and carrier. Some carriers let you delete voicemails from blocked numbers automatically, while others require you to delete them yourself.

The person who is blocked won't receive a message saying they've been blocked. From their perspective, their call straightforward won't go through, or they may hear a message from your carrier saying the call cannot be completed.

Block numbers using your carrier's service

In addition to blocking numbers on your phone itself, your carrier (Verizon, AT&T, T-Mobile, or another provider) may offer its own call-blocking service. These services work at the network level, meaning they block calls before they even reach your phone.

To set up carrier-level blocking, contact your provider directly or check their website. Many carriers offer free basic blocking or premium services with more features. Carrier blocking is sometimes more effective for spam calls because it stops them before they reach your device, but it requires a separate setup from your phone's built-in blocking.

Frequently Asked Questions

Can a blocked person tell they've been blocked?

No. A blocked caller won't receive a notification saying they've been blocked. Their call straightforward won't connect, and they may hear a generic message from your carrier. They have no way to know for certain whether you blocked them or if your phone is off.

Can blocked numbers still leave voicemails?

Yes, blocked numbers can still leave voicemails on most LG phones. You won't get a notification when they do, but if you check your voicemail folder manually, you may see their messages. Some carriers let you configure this differently, so check your voicemail settings if you want to prevent blocked callers from leaving messages.

What if I block a number by mistake?

Open your Phone app, go to your blocked list (usually in settings or the menu), find the number, and tap "Unblock." The person can when ready call and text you again. There's no waiting period or confirmation needed.

Do I need to block a number on both my phone and my carrier's service?

No. Blocking on your phone alone is usually enough. If you want extra protection against spam, you can set up carrier-level blocking as well, but it's not necessary. Phone-level blocking is faster and works for any number you choose.

Will blocking a number stop them from seeing my location or social media?

No. Blocking a phone number only stops calls and texts. It doesn't affect social media, location sharing, or other apps. If you want to prevent someone from contacting you on other platforms, you'll need to block them separately in those apps.
