When you use public Wi-Fi

No matter whether you’re going, on an overnight jaunt or a month-long international journey, it’s always a good idea to let bharti jha friends or family back home know.

When you use public Wi-Fi, hackers looking to steal valuable information can access your data including credit card or Social Security numbers. If you do need wireless Internet service, set up a virtual private network (VPN) that will allow you to access the Internet securely while traveling.

There are steps you can take to make your room safer. Lock and dead-bolt the door and keep your windows shut. You can buy a jammer, which is a portable device that slips under the door for another layer of protection.

Travel security precaution is to know whom to call in an emergency. Get the contact information for the nearest embassy or consulate, police station, and other local emergency departments.
