How To Block Texts on an Android Device

Text messaging is a convenient way to communicate, but unwanted texts can be annoying and intrusive. Fortunately, Android devices offer multiple ways to block texts, giving you control over who can send messages to your phone. This comprehensive guide covers several methods for blocking texts on your Android phone or tablet.

Use Android’s Built-In Blocking

Android’s default Messages app provides a simple way to block texts right from an unwanted conversation:

  1. Open the Messages app and select the conversation with the number or contact you want to block.
  2. Long press on the conversation. A menu will appear.
  3. Tap “Block & report spam”. You’ll have the option to report the sender as spam.
  4. Confirm that you want to block the number.

The number will now be blocked from sending you messages. You can find a list of blocked contacts and unblock them in Messages Settings > Blocked contacts.

Block Numbers Using Contacts

You can also block contacts directly from the Contacts app:

  1. Open Contacts and select the contact you want to block.
  2. Tap the menu icon (3 vertical dots) in the top right corner.
  3. Select Block number.
  4. Confirm that you want to block the contact.

This will prevent them from sending messages and calling.

Use a Third-Party App

If the built-in options don’t meet your needs, download a call and text blocker app from the Play Store. Popular options include Truecaller, Calls Blacklist, and Hiya.

These apps provide advanced spam detection, blacklists, whitelists, keyword blocking, and more. Most will require additional permissions or subscriptions for full functionality.

Block Texts on Your Carrier Account

Many carriers allow you to block texts and calls right from your account. The specifics vary between carriers, but you’ll generally find a call/text blocking option after logging into your account online or in the carrier’s app.

You can block specific numbers or use blanket blocking settings like blocking all unknown numbers. This can be a simple solution if you receive a lot of spam texts.

Set Do Not Disturb to Block Text Notifications

Android’s Do Not Disturb mode allows you to silence notifications during set times or calendar events. You can customize it to block visual interruptions from texts:

  1. Go to Settings > Sound & vibration
  2. Tap Do Not Disturb
  3. Choose if you want it enabled manually, on a schedule, or based on events
  4. Under the Behavior section, customize notifications to block sound and visuals from texts

With this approach, your phone won’t light up or make sounds when receiving texts from blocked contacts during enabled times. The texts will still be visible in your Messages app.

Use App Rules to Block Messaging Apps

App rules in Android’s Digital Wellbeing settings let you block access to apps during specific times, set time limits, and more.

To block messaging apps:

  1. Go to Settings > Digital Wellbeing & parental controls
  2. Tap App rules
  3. Tap Add rule
  4. Choose a messaging app you want to block
  5. Set a schedule for when it will be blocked
  6. Tap Save

You can create multiple rules to block access to messaging apps including SMS, WhatsApp, Facebook Messenger, and others. This lets you control when your child can use messaging apps.


With Android’s built-in tools, third-party apps, carrier account settings, and screen time controls, you have several ways to stop unwanted texts from reaching your phone. Try out the options to find the best text blocking method for your needs.
