Street telephone booths were once standard equipment in various cities, but with the popularization of mobile phones, many public telephone booths have gradually lost their practical function and gradually disappeared from people's vision. The digital upgrade of public telephone booths in Shanghai this time has made their practicality keep up with the times and "iteratively upgraded", which is gratifying. It is reported that these public telephone booths not only provide a 3-minute free call service, but also integrate various convenient services such as one click call and free charging.

These renovated public telephone booths not only adorn the street scenery, but also add warmth to the city. As some tourists experience: 'Just got off the train, my phone ran out of battery, and I want to make a call to my family. This kind of free phone is quite convenient' - helping those in need solve urgent needs, meeting the public's' unexpected needs', and making urban public services full of 'human touch'.

Currently, urban renewal actions are being carried out in many places. Responding to public demands and adapting to the development of the times is the basic path for urban renewal. At the "Ministerial Channel" of this year's National People's Congress and the National People's Congress, the Minister of Housing and Urban Development stated that "urban renewal not only needs to transform old and old ones, fill gaps, but also needs to have innovative thinking and empower urban renewal with technology." From this perspective, Shanghai's digital upgrading of public telephone booths is also one of the measures to promote the construction of urban digital infrastructure. The exploration of "small incisions" similar to urban renewal and grassroots governance, leveraging the "significant improvement" of public services, is worth praising.

Currently, many cities are actively promoting the transformation and upgrading of public infrastructure. For example, Beijing has carried out pilot construction of public telephone booths in areas such as Tiantan Park, Friendship Hospital, Beijing South Station, and Sanlitun, featuring digitization, landscaping, and integration, with functions such as information navigation, mobile phone charging, and 5G micro base stations. Making public services more attentive and thoughtful reflects the refinement and humanization of urban governance, as well as the people-oriented concept and feelings for the people.
