How to block text messages from someone

What is a spam message?

A spam message is any kind of unwanted or unsolicited communication, often sent in bulk over the internet or through an electronic messaging service. On mobile, unwanted text messages usually come from unknown numbers or as robotexts sent by auto-dialers. Spam texts often promote a product or service.

Spammers don’t just use SMS messages. Spam can be sent in other forms, too, including phone calls from spam phone numbers, not to mention all the spam emails that inundate our inboxes.

Most spam messages are relatively harmless, and filtering out spam is usually simple. But while most spam messages don’t pack computer viruses or other malware, some spammers may be phishing to harvest your personal data.

How to stop spam text messages

If you’re wondering how to block texts, there are a number of quick and easy steps you can take to stop getting messages from a specific number and reduce your overall vulnerability to spammers and the online scams they perpetuate.

There are a range of built-in and third-party apps for filtering and blocking spam texts. And there are various organizations dedicated to investigating unlawful spamming and spoofing to which you can report spam texts and other potentially dangerous messages.

Don’t respond

No matter how annoying it is to receive text messages from random numbers, do not respond to them. In fact, that’s one of the worst things you can do, because it lets the spammers know that your cell phone number is active, and you could invite a barrage of more robotexts and other nuisance messages.

Block numbers

A simple way to keep scam text messages out of your inbox is to block spam numbers on your phone. This works on both iPhone and Android devices, and it prevents messages or calls from the blocked number from reaching you. Note that spammers may be able to bypass the block if they spoof someone else’s phone number.

Report spam messages to your mobile network provider

Scammers may be getting smarter, but mobile service providers are also getting better at identifying and shutting down spam phone numbers. Reporting suspicious or spam messages to your carrier helps protect yourself and others by preventing similar texting scams in the future. AT&T, Verizon, or T-Mobile customers can do this by simply forwarding the spam message to 7726.

You can also report a suspicious phone number and lodge a complaint with the relevant authorities in your jurisdiction. In the US, unwanted texts and internet scams can be reported to the Federal Trade Commission via the National Do Not Call Registry. You can also add your number to their Do Not Text list, which bans spammers and telemarketers from targeting you.

Use spam-blocking apps

For an extra layer of spam security, use an app to proactively block text messages from scammers and spam phone numbers. These apps draw upon enormous databases that are constantly updated to automatically block text scams and spam messages.

Best text blocking apps for Android

  • VeroSMS

    VeroSMS doesn’t have access to your texts, and none of your data is sent to its servers. You can customize your contact list, banning outside callers while preventing verified contacts from being blocked.

  • SMS Shield

Never click on any link in a text message or email unless it comes from a trusted source. Spam text messages are a classic vehicle for phishing scams that try to coax you into clicking links that can lead to pharming websites that steal your data or inject adware or other malware into your device.

Protect your personal info

Legitimate companies won’t ask for sensitive personal information such as your address, account passwords, or government identification numbers — especially not via SMS. Keep your personal data private or you risk becoming a victim of identity theft.

If you are asked to hand over personal data, report the spam text message immediately and take steps to block unwanted messages from anyone or any number sniffing around for your personal details.

Review your mobile bill regularly

Some spam advertising campaigns and other mobile scams force your cell phone to call or text premium numbers, thereby running up your bill. Review your mobile statements and look for any unusually high charges, unexpected data usage, or anything unusual.

Use your phone’s built-in spam-blocking features

Check your phone’s security settings and use any built-in privacy features like call blocking, caller ID, spam filters, and any other anti-spam controls to help block unwanted text messages, spear phishing attempts, or other scams.
