Final answer:
Using public Wi-Fi networks is not a best practice when traveling overseas with a mobile device due to security risks. Instead, using a VPN, keeping software updated, and using strong passwords and encryption are recommended to protect personal and financial information.
Step-by-step explanation:
The practice that is not recommended when traveling overseas with a mobile device is using public Wi-Fi networks. Public Wi-Fi is often unsecured, which increases the risk of your personal information being compromised. When you are abroad, it's essential to protect your credit and debit cards and other sensitive information. Utilizing a VPN (Virtual Private Network) can safeguard your data by encrypting your internet connection, making it much harder for potential attackers to access your information.
Other best practices include keeping software updated to ensure that security patches are applied, and using strong passwords and encryption to protect the data on your mobile device. These steps, in addition to not using public Wi-Fi without a VPN, can help keep your digital wallet and personal information secure while you travel.
It's also advisable to use anti-virus software on your computer and mobile devices, and to notify your bank when you change your address or phone number in order to maintain the security of your banking information.
