Every smartphone lets you filter spam texts: Here’s how to do it

Scams often start with a text from an unknown person that should, but doesn’t, raise a red flag. Not seeing these spam texts in the first place just adds a layer of protection.

Smartphone users overwhelmed by these spam messages may be surprised to learn that they already have a powerful defense at their fingertips. Both Apple and Google include tools in their mobile operating systems that can automatically filter and silence suspicious text messages — no third-party apps required.

How iPhone users can filter spam texts

Apple’s iOS includes a feature called Filter Unknown Senders, which separates messages from people not in your contacts and reduces notifications from likely spam.

To turn it on, iPhone users should:

1. Open Settings
2. Tap Messages
3. Scroll down and switch on Filter Unknown Senders

Once enabled, messages from unknown numbers are routed to a separate tab in the Messages app. Users won’t receive notifications for those messages, making it harder for scam texts to interrupt their day. Apple also allows users to report junk messages directly from the Messages app, which helps improve spam detection over time.

How Android users can block spam messages

Android devices, particularly those using Google Messages, offer a similar feature called Spam Protection.

To enable it:

1. Open the Messages app
2. Tap the three-dot menu in the upper-right corner
3. Select Settings, then Spam protection
4. Turn on Enable spam protection

With this setting active, Android phones automatically detect and move suspected spam texts to a separate folder. Users can review the messages if needed or delete them permanently. Android also allows one-tap reporting of spam, which helps refine future filtering.

Why this matters

Spam texts aren’t just annoying — they can be dangerous. Many are designed to trick users into clicking malicious links, sharing personal information, or sending money. Enabling built-in spam filters adds an extra layer of protection and reduces exposure to these scams.

While no system is perfect, consumer advocates say turning on these settings is one of the easiest and most effective steps users can take to protect themselves. Combined with basic precautions — such as avoiding unknown links and never sharing verification codes — spam filtering can make smartphones safer and quieter.

Most common text scams

Text-message scams – often called “smishing”)= – are one of the fastest-growing ways criminals target consumers. While the wording changes constantly, most scams fall into a few well-known patterns. Here are some of the most common ones to watch for:

Delivery and package scams

These messages claim there’s a problem with a shipment from USPS, UPS, FedEx, or Amazon. The text usually includes a link and urges quick action, such as confirming an address or paying a small “redelivery” fee. The link leads to a fake website designed to steal personal or payment information.

Bank and fraud alert scams

Scammers pose as banks or credit card companies, warning of “suspicious activity” on your account. The message may ask you to click a link, call a number, or reply “YES” to verify your account. The goal is to capture login credentials or trick you into authorizing fraudulent transactions.

Government impersonation scams

These texts pretend to come from government agencies like the IRS, Social Security Administration, or state motor vehicle offices. Common claims include unpaid taxes, suspended benefits, or missed toll payments. Legitimate government agencies rarely — if ever — initiate contact by text.

Job and work-from-home scams

Scammers send unsolicited job offers promising high pay for minimal work, sometimes claiming to represent well-known companies. These texts often lead to fake interviews conducted by text or messaging apps, followed by requests for upfront fees or personal information.

“Wrong number” and conversation-starter scams

These texts begin innocently, such as “Hey, are we still on for dinner?” If you respond, the scammer builds a friendly conversation that can eventually lead to investment scams, romance scams, or cryptocurrency fraud.

Account verification and password reset scams

Messages claim someone tried to log into your email, social media, or streaming account and urge you to “secure” it immediately. Clicking the link sends you to a convincing but fake login page that steals your credentials.
