Internet, email and mobile phone fraud

Mobile phone scams

Smartphones are mini-computers, so take all the same precautions with them as you would with your own computer at home.

What you should know

If you use an online banking app, only use the official app provided by your bank. If in doubt, contact your bank to check.

Only download apps from official app stores, such as:

• Apple App Store
• Android Marketplace
• Google Play Store

Downloading them from unofficial or unknown sources could infect your phone with a virus.

Keep your phone’s operating system updated with the latest security patches and upgrades. Your operating system provider normally sends these.

Never give your mobile banking security details, including your passcode, to anyone else and don’t store them on your phone.

For added security set up a password or PIN to lock your mobile.

Just like on your computer, you can get antivirus tools for your mobile; use a reputable brand. Some banks offer free antivirus software for their customers’ phones. Check your bank’s website for more information.
