Phone and Text Message Scams: The Most Common Types and How to Protect Yourself
A message saying your order is stuck, a call informing you that you've won a prize, a contact urgently requesting money. The phone and text message scams They change their clothes all the time, but almost always follow the same script: create a sense of urgency, gain your trust, and ask for information or money.
In this guide you will learn about the most common scams, recognize the warning signs, and find out what to do if you or someone in your family falls victim to one of them.
Why do phone scams work so well?
Scammers rely on two factors: haste and emotion. When the message mentions an urgent problem, a family member needing help, or an expiring prize, people act before thinking. Furthermore, many scams use real information, such as your name or the bank where you have an account, obtained from data breaches. This makes the approach seem legitimate.
The best defense is to know the patterns. Once you recognize the pattern, it becomes much easier to be suspicious.
1. Order fee scam
How it works: You receive an SMS or text message saying that your order is being held and that you need to pay a small redelivery or customs fee. The message includes a link to a page that mimics the website of a delivery company, where you enter your card details or pay a code.
Warning signs:
- You're not expecting any deliveries or you don't remember buying anything from abroad.
- The link has a strange address, either shortened or different from the official website.
- The message gives a short deadline, such as "pay today or the package will be returned".
How to protect yourself: Do not click the link. If you have a purchase on its way, check the tracking by typing the official website address yourself or opening the app of the store where you made the purchase.
2. Fake prize scam
How it works: You receive a call or message informing you that you've won a prize, a car, or a cash prize. However, to claim the prize, you need to pay a fee, provide bank details, or share a code received via SMS.
Warning signs:
- You did not sign up for any promotion.
- They ask for advance payment to "release" the prize.
- They ask you to keep it a secret or decide on the spot.
How to protect yourself: Legitimate promotions don't charge for prize delivery. Hang up and, if you want to confirm, contact the company through the official channels you can find yourself.
3. The "I changed my number, send me a Pix" scam“
How it works: Someone sends a message from a new number, with a photo of a son, nephew, or friend, saying they've changed their phone number. After a short conversation, comes the request: pay an urgent bill or make a transfer, with the promise to return it the next day.
Warning signs:
- The person avoids answering phone calls or video calls.
- The writing style is different from usual.
- The account for the payment is in someone else's name.
How to protect yourself: Before making any transfers, call the person's old number or speak to someone close to them. Another tip is to ask a question that only they would know the answer to.
4. Fake bank call center scam
How it works: You receive a call from someone posing as an employee of your bank, informing you about a suspicious purchase on your card. To "cancel" the purchase, the person asks for your password, the code received via SMS, that you install a remote access app, or that you transfer the money to a "secure account.".
Warning signs:
- They ask for a password, verification code, or complete card details.
- They ask you to install some app during the call.
- They talk about a "secure account" or "protection account" for where to take your money.
How to protect yourself: The bank does not ask for passwords or transfer information over the phone. Hang up and contact them yourself through the official app or the number printed on the back of your card. If possible, call from a different device, as in some cases the line may still be connected to the previous call.
