Spam text messages are annoying and sometimes dangerous. They may try to trick you into clicking links or giving away personal information.
The good news is you can block spam text messages and reduce how many you receive.
This guide explains how to do it on both iPhone and Android phones.
First: Do Not Reply to Spam Messages
Even if the message says:
“Reply STOP to unsubscribe”
Do not reply unless you are sure it’s from a real company. Replying can tell scammers your number is active.
How to Block Spam Texts on iPhone
Method 1: Block the Number
- Open the Messages app
- Open the spam message
- Tap the name or number at the top
- Tap Info
- Scroll down and tap Block this Caller
- Confirm by tapping Block Contact
You will no longer receive texts or calls from that number.
Method 2: Filter Unknown Senders
This helps hide messages from numbers not in your contacts.
- Open Settings
- Scroll down and tap Messages
- Turn on Filter Unknown Senders
Now messages from unknown numbers go into a separate list.
Method 3: Report Junk Messages
- Open the spam message
- Tap Report Junk (if you see it)
- Tap Delete and Report Junk
This helps Apple reduce spam for others too.
How to Block Spam Texts on Android
Steps may vary slightly by phone brand, but they are very similar.
Method 1: Block the Number
- Open the Messages app
- Open the spam message
- Tap the three dots in the top corner
- Tap Details or Block & report spam
- Tap Block
The number will no longer be able to message you.
Method 2: Turn On Spam Protection
Many Android phones include built-in spam filtering.
- Open the Messages app
- Tap the three dots in the top corner
- Tap Settings
- Tap Spam protection
- Turn on Enable spam protection
Your phone will now try to detect and block suspicious messages.
Extra Tip: Use Your Mobile Carrier’s Spam Tools
Phone companies often provide free spam blocking.
You can visit your carrier’s website or call customer service to ask about:
- Spam text filtering
- Blocking unknown numbers
Signs a Text Message Is Spam
Be careful if a text message:

- Comes from a strange or very long number
If unsure, do not click anything.
What If You Clicked a Spam Link?
Don’t panic.
- Close the webpage immediately
- Do not enter personal information
- If you entered details, contact your bank right away
- Consider asking a trusted family member for help
