Having to pay for wi-fi service at your hotel seems petty and is definitely annoying. So, when you are in your hotel room and you notice a “free wi-fi” network, it is very tempting to log on. Beware of these supposedly free networks!
Many of these advertised free hotspots are scams, and the thieves running the operation will collect all the data you submit through the wi-fi signal. If the advertised network does not ask for a password, this should be a red flag.
Before you connect to a network, free or otherwise, make sure it is legitimate. Talk to the hotel staff and inquire about preferred networks.
While you should enjoy your travels thoroughly, it is prudent to be aware of possible scams out there. Be safe and enjoy your trip!
