Smishing and Vishing: Fake Text and Phone Scams

A fake text message is a fraudulent SMS or messaging-app communication designed to make you click a link, provide information, send money, or take another action. These messages are a common form of smishing, or SMS phishing.

You receive a text saying your bank account has been locked. A few minutes later, someone calls claiming to be from your bank’s fraud department. They know your name, reference a recent transaction, and tell you that you need to act immediately.

Should you trust them?

Scams that arrive through text messages and phone calls are becoming increasingly convincing. Cybercriminals use familiar brands, urgent requests, spoofed contact information, and even artificial intelligence to make fraudulent communications appear legitimate.

Two common forms of these attacks are smishing and vishing. Smishing uses text messages to manipulate victims, while vishing uses voice communication, typically phone calls or voice messages. Both are forms of social engineering designed to convince someone to reveal information, click on a malicious link, transfer money, or take another action that benefits the attacker.

Understanding the difference between these attacks is important, but knowing how to identify and respond to a malicious text message or suspicious phone call is even more important.

What Do Vishing and Smishing Refer To?

Smishing and vishing are variations of phishing.

Smishing combines “SMS” and “phishing” and refers to phishing attacks delivered through text messaging. A scammer may send a message pretending to be a bank, delivery company, government agency, employer, coworker, or another trusted organization.

Vishing stands for “voice phishing.” These attacks use phone calls, voice messages, or other voice-based communication to persuade someone to provide information or take action.

Both attacks rely heavily on social engineering. Instead of exploiting technical vulnerabilities, the attacker attempts to exploit human behavior.

Vishing vs. Smishing: What’s the Difference?

Neither channel is automatically more dangerous than the other. The goal is the same: to convince you to trust communication that you shouldn’t.

How to Identify a Fake Text Message

Knowing how to identify a fake text message can help you avoid clicking a malicious link or giving a scammer information.

Knowing how to identify a fake text message can help you recognize smishing scams before you click a malicious link, provide sensitive information, or send money. Fake text messages often impersonate banks, delivery companies, government agencies, employers, and other organizations you recognize.

Start by asking whether the message was expected.

An unexpected message isn’t automatically a scam. Businesses, schools, healthcare providers, delivery services, and other organizations may legitimately contact you by text. However, an unexpected message deserves a closer look when it asks you to take an unusual action.

Watch for these warning signs:

1. The Message Creates Urgency

Scammers don’t want you to stop and investigate.

A message might say:

• “Your account will be closed today.”
• “Your payment failed. Update your information now.”
• “Suspicious activity was detected. Verify your account.”
• “You have an unpaid toll.”
• “Your package cannot be delivered.”
• “Respond immediately to avoid a penalty.”

Urgency is designed to make you react before you think.

2. You’re Asked to Click a Link

Unexpected links should always receive additional scrutiny.

A link might lead to a fake login page designed to steal your username and password, or it could direct you to a website that requests financial or personal information.

Don’t assume a link is safe simply because the message appears to come from a company you recognize.

Instead, navigate to the organization’s official website or app yourself.

3. The Sender Is Unfamiliar

An unknown phone number is an obvious warning sign, but a familiar-looking sender doesn’t guarantee that a message is legitimate.

Scammers can manipulate sender information, impersonate organizations, or make messages appear to come from someone you know.

4. The Request Doesn’t Make Sense

Consider the context.

Did you actually order the package? Do you have an account with the company? Were you expecting a payment request? Does the person normally contact you this way?

If the answer is no, don’t assume you need to act just because the message sounds convincing.

5. The Message Requests Sensitive Information

Be especially cautious if an unexpected message asks for:

• Passwords
• Social Security numbers
• Credit card information
• Bank account information
• Authentication codes
• Employee credentials
• Personal identification information

Legitimate organizations generally have established processes for handling sensitive information. Don’t provide it simply because someone asks.

Common Smishing Scams

Smishing attacks can take many forms, but several scenarios appear frequently, including:

Fake Delivery Messages

You may receive a text claiming that a package couldn’t be delivered or that you need to pay a small fee.

The message includes a link that appears to lead to a shipping company’s website.

The goal may be to steal your payment information or credentials.

Bank and Fraud Alerts

A message may claim that your account has experienced suspicious activity.

It might tell you to click a link or call a number to “verify” a transaction.

Instead of resolving a real security problem, the scammer may be trying to obtain your banking credentials.

Toll and Payment Scams

Another common tactic involves messages claiming you have unpaid tolls or fees.

The small amount requested can make the message seem believable. However, the link may lead to a fraudulent payment page.

Wrong-Number Messages

A seemingly innocent message such as “Are we still meeting for dinner?” can be the beginning of a scam.

After you respond, the conversation may gradually shift toward personal topics, financial opportunities, cryptocurrency, employment offers, or other fraudulent schemes.

iMessage Scams and Group Text Scams

iMessage scams are a form of messaging-based social engineering. Like other smishing attacks, they may use fake alerts, malicious links, impersonation, or requests for personal and financial information.

Scammers may also use group messages or messaging platforms such as iMessage to make communication appear more legitimate.

Being included in a group conversation doesn’t mean the participants or information are trustworthy.

If you don’t recognize the people involved or the conversation seems unusual, don’t interact with links or attachments simply because they appeared in a group message.

Why Are Smishing Attacks Particularly Effective?

Smishing attacks are particularly effective because text messages are immediate, personal, and familiar. People are accustomed to checking and responding to texts quickly, which gives scammers an opportunity to create urgency before the recipient has time to verify the message.

In May 2026, the Denver County Court and Denver Police Department warned the public about a text scam involving unpaid tolls and parking or speeding violations. The scam mimicked a court summons, telling recipients to pay a $6 fine or appear in court. Hundreds responded to the fraudulent message by arriving at the Denver City and County Building in response to the fake court order.

The problem becomes even more difficult when attackers combine multiple communication channels.

For example:

Text → phone call → malicious website

A scammer might first send a fake fraud alert by text. When the victim responds, the attacker calls and pretends to be a bank employee.

Each interaction makes the next one seem more credible.

Why smishing works:

• Text messages are typically read quickly.
• People often trust familiar names and organizations.
• Mobile devices make it easy to click links immediately.
• Urgent messages discourage careful verification.
• Attackers can impersonate trusted organizations.
• Smishing can be combined with phone calls or other attacks.

How to Recognize a Vishing Scam

Vishing attacks use many of the same psychological tactics as smishing, but the attacker has the advantage of speaking directly with you.

Be cautious when an unexpected caller:

• Claims to represent your bank or another trusted organization
• Creates an immediate sense of danger
• Requests payment
• Asks for account credentials
• Requests an authentication code
• Tells you to move money
• Asks you to install software
• Wants you to stay on the phone while completing an action
• Tells you not to contact anyone else
• Becomes aggressive when you ask questions

A convincing voice doesn’t prove that the caller is legitimate.

Caller ID doesn’t prove it either.

If the caller claims to represent an organization, end the call and contact that organization using a phone number from its official website, mobile app, statement, or another trusted source.

Don’t Engage with the Scammer

If you recognize a message as suspicious, you may wonder: What is the best message to send to a scammer?

Usually, no response is the best response.

Don’t try to convince the scammer that you’ve identified the fraud. Don’t provide fake personal information. Don’t click on a link to investigate. And don’t continue a conversation simply to see what happens.

Responding can confirm that your phone number is active and may encourage additional attempts.

Instead, use your phone’s reporting features, block the sender when appropriate, and delete the message after preserving any information needed for reporting.

What If You Already Clicked?

Don’t panic.

If you clicked a suspicious link, your next steps depend on what happened.

If you entered a username or password, change the password immediately on the legitimate website or app. If you reused that password elsewhere, change it there as well.

If you provided financial information, contact your financial institution using a trusted phone number.

If you entered an authentication code, contact your organization’s IT or security team immediately.

If you download something or installed software, disconnect the affected device from the network if appropriate and contact your organization’s IT or security team.

Most importantly, report the incident quickly.

Reporting a mistake gives your security team an opportunity to investigate, protect other users, and potentially prevent a larger incident.

How to Respond to Suspicious Texts and Calls

A simple process can help you respond safely:

• Stop. Don’t immediately click, reply, or provide information.
• Inspect. Look at the sender, phone number, link, request, and context.
• Verify. Contact the organization or individual through a trusted communication method.
• Report. Follow your organization’s reporting process or report the scam to the appropriate authority.
• Delete or block. Once you’ve preserved any information needed for reporting, remove the communication.

The most important step is verification. If a message says your bank needs information, open your bank’s official app yourself.

If someone claims to be a coworker, contact that coworker using your organization’s directory, or a vendor asks you to change payment information, verify the request through an established business contact.

Don’t use the phone number or link provided in the suspicious communication to verify it.

How Organizations Can Help Employees Recognize Smishing and Vishing

Employees shouldn’t be expected to identify every scam without support.

Organizations can reduce risk by incorporating smishing and vishing into security awareness programs alongside traditional email phishing.

Training should cover:

• Common smishing and vishing tactics
• How to identify suspicious requests
• Social engineering warning signs
• Safe handling of links and attachments
• Verification procedures
• Incident reporting
• MFA and authentication security
• What to do after clicking or responding to a scam

Organizations can also use phishing simulations and awareness exercises to reinforce these lessons.

Phishing awareness training addresses evolving phishing tactics, including phone-based vishing, text-based smishing, QR code phishing, social media scams, and AI-enabled phishing threats.

The goal isn’t to make employees suspicious of every text or phone call. It’s to help them recognize when communication doesn’t fit the situation and know what to do next.

Make Verification a Habit

Smishing and vishing attacks work because they exploit something every organization depends on, trust.

A text can look like it came from your bank. A phone call can sound like it came from your coworker. A message can create enough urgency that you act before asking whether the request makes sense.

The answer isn’t to distrust every communication.

It’s to build the habit of stopping and verifying when something seems unusual.

Don’t click first. Don’t respond first. Don’t assume a familiar name, phone number, caller ID, or logo proves authenticity.

Stop. Verify. Report.

Should I reply to a scammer?

Generally, no. Avoid engaging with suspicious messages. Use your device’s reporting functionality and follow your organization’s procedures when applicable.

What should I do if I receive a suspicious call?

Don’t provide information or follow instructions simply because the caller sounds legitimate. End the call and independently contact the claimed organization using trusted contact information.
