Phone Scam — Recognize and Avoid Fraud Calls

Phone scams are rising worldwide. Learn the warning signs, protect your personal data, and discover what to do if you suspect a fraudulent call.

Most common phone scams

Fake tech support

A caller claims to be from Microsoft, Apple, or your internet provider, saying your computer is infected. They ask you to install remote-access software. No legitimate company calls customers this way.

Bank fraud (vishing)

The caller spoofs your bank's phone number, quotes personal details, and asks for a verification code or transfer to a 'secure account'. Banks never ask for codes over the phone.

Tax or government impersonation

A fake IRS, HMRC, or tax office agent threatens arrest or seizure unless you pay immediately. Real tax authorities communicate by mail first.

Prize or lottery scams

You have 'won' a prize, trip, or inheritance. To claim it, you must pay fees or taxes upfront. If you did not enter, you did not win.

SIM swap fraud

The scammer convinces your carrier to transfer your phone number to a new SIM card. They then intercept your SMS verification codes and access your bank accounts.

Warning signs — the scam checklist

Artificial urgency: "You must act now or your account will be suspended"
Request for sensitive info: passwords, PINs, verification codes
Payment via unusual methods: gift cards, crypto, Western Union
Threats: police, court, bailiff, account seizure
Too-good-to-be-true promises: lottery wins, inheritances, refunds

How to protect yourself

Never give in to pressure

Legitimate organizations never threaten immediate sanctions. Take time to verify the caller independently.

Never share codes

Your bank, carrier, or the police will never ask for your password or SMS verification code over the phone.
