Back in 2013 I was on a business trip to Ho Chi Minh City (HCMC) in Vietnam. And to my surprise, I learned that there was free public WiFi avaiable at one park in the city centre only.
Now it seems they have scaled it up and it is available all over HCM Square. Many western developed countries have to seriously make an effort to catch up with the pace of technology adaption in Asia.
