Because I know I can trust my carrier network far more than I can trust a random, public wireless option. You have to understand that even when you take all necessary precautions with a public wireless network, you can never know for sure if it’s safe. Although using my phone’s hotspot does use up plan data, it’s worth the security it offers when I know I need to transmit secure information. Also: The best hotspot devices (besides your phone)If you have to type a password for an account, if you need to log into your bank, if you have to type in a credit card number… use your phone or your phone’s hotspot.
