Hi, I would an interesting blog that the old phone booths in NYC are being converted into WI-Fi hotspots. I think it is a wonderful way to reshape the city streets without changing the iconic booths. See it , https://www.acanac.com/blog/general-category/sidewalk-labs-whats-old-is-new-again/ Free internet is a concept which is gaining momentum. But I am skeptical about availing the free internet. There has to be some hidden elements in it. Maybe the companies are watching our search patterns for advertising. I would use the free internet only if I am sure my phone is secured. Are there any apps or tools to secure the internet for Android marshmallow?
