Be Warned of “Free Wifi”
FREE WIFI! Many airports, hotels or restaurants Wi-Fi ask you for your email to register.
DO NOT GIVE THEM your correct email because they sell your email to companies. This is how they make money. This is why you get random emails from companies you never purchased products from.
I learned this the hard way when I went to a restaurant in Germany during one of my trips. I got back to LA and received nonstop emails from German companies. A TON. This happens everywhere including the US and Asia.
They sell your email to different companies. Even if you unsubscribe, they will still keep selling your email information. It was a nightmare for me. For over a year, my inbox was inundated by random German emails selling anywhere from candy, porn, to crypto.
Even if you provide the Wi-Fi company with an incorrect email, you can still access Wi-Fi. Because 95% of the time, they do not verify.
