How to have a safer 2018

❚ Don’t unplug — even if you’re on vacation.

The world doesn’t stop when you’re away, and disaster can strike anytime, whether you’re on a Caribbean cruise or touring California’s wine country. Pack your cellphone, keep it on and subscribe to news alerts from your favorite source.

❚ Get an international SIM card for your phone or a reliable international plan.

Some of the most frantic moments during the last few security scares came when loved ones couldn’t communicate with visitors affected by disasters. I use Google Fi (fi.google.com), which doesn’t charge any international roaming fees and charges a reasonable fee for data.

❚ Download the State Department’s Smart Traveler app (travel.state.gov).

Also, sign up for State’s Smart Traveler Enrollment Program (STEP), which allows U.S. citizens and nationals traveling and living abroad to enroll their trip with the nearest U.S. embassy or consulate.
