usually most business in my area have hot spots that their customers can connect to. I think some cities have public areas near parks and such.
I feel free hot spots may not be worth the risk of using on your own personal mobile devices like laptops, tablets, and smartphones because of greater security risks from using free wi-fi if the router and router firewall are using outdated firmware or got hacked by a criminal. The owner of the internet connection maybe untrustworthy, and collect data on its free users to stalk them, or somehow steal their private information like e-mail to send spam to their e-mail, or sell their username and passwords to criminals.
The government who owns and operate the wi-fi connection may come and arrest users who used their connection to post something that the government does not agree with, or think you may commit a crime because you searched for terms like grand theft auto, street fighter, and swords on the internet when connected to their Wi-Fi.
I personally feel it is safer to use a computer at a library, internet cafe, or work for non-important tasks which don't require you to login to an online user account for a website, and allow reading website articles, or video from the front page without the need to sign-in with a username and password.
Users have to be careful when using free wi-fi since there are criminal hackers who make free wi-fi hot spots from their laptops, and their own data plan to steal strangers' data, and install malware and ransomware onto a PC like infecting your computer with a WannaCry-Style Ransomware which uses a Microsoft Windows networking vulnerability to infect a PC.
I think if you use your laptop, smartphone, and tablet for accessing your online bank account, work, or other important tasks, or storing important data, it would not be worth it to use free hot spots, and it would be safer to use the internet at home, or subscribe to a paid cellular internet data plan for your tablet or laptop if you
absolutely need to use the internet when not at home or work.
