18. Protect your online security.
To protect your information and avoid having to use public wifi to connect, consider purchasing a VPN for secure access. Make sure your debit and credit card companies know you’re traveling.
19. Get an unlocked smartphone for travel abroad.
Your wireless plan may let you add overseas options, but you’ll pay a premium for it. Buy an unlocked phone and a SIM card with a data plan in your destination country. You’ll have low-cost mobile Internet access and a local phone number.
