I live in the Los Angeles area and wanted to see if there was any Wi-Fi in my area and saw a "TWC Wi-Fi" public wi-fi hotspot. I connected to it for kicks and saw that they were offering a 30 day, 30 min/day free trial. No credit card required, just click on the "free trial" sign up when you get to the wi-fi connection splash page on your device and register with a valid cell phone number. They will send you a code via text to connect to the wi-fi and you're good to go.
I know that my area in Los Angeles is covered in these hotspots and it's always nice to have a reliable wi-fi signal in case my reception is spotty, even for 30 minutes a day.
