"Subscribers should be cautious about using free wireless hotspots. In particular, you should avoid sending sensitive or personal information over these untrusted networks. Free wi-fi hotspots can be found in coffee shops and public establishments, offering convenient internet access over a wireless connection. You can connect to these hotspots using devices such as mobile phones or laptops with wireless capabilities. However, it is important to be aware that most of these hotspots are unsecured, meaning that all the information you send across them is vulnerable."
