Is Wi-Fi safe overseas?

Episode 1038 (15:48)

Nick from Anaheim, CA

Nick is heading to Paris and he wants to know if he can bring his T-Mobile flip phone. Leo says it would be a good idea to contact T-Mobile and get an international calling plan. He's also planning on bringing his laptop, but he's worried about Wi-Fi security. Leo says it's about as safe there as it is here, meaning that it's best to use encryption if he's visiting any sites that are public. He should avoid banking online if he can. Banks will encrypt his traffic, though. The greater risk is his email and logging in, so that's where he'll want to be encrypted. Wi-Fi is essentially a radio signal and data packets can be plucked out of the air. He could use a virtual private network (VPN) for additional security.
