Usim Public / Public Phone

Usim Public
Usim Public

Do you know how much money has been spent on maintaining the public
phones which need for emergencies and people like foreign workers, tourists, low-income groups?
In korea, each public phone costs lots of money around 750$ every year. As a result, the public phones make serious losses anually in Korea approximately 75 billion dallors.

To solve this problem, I would like to suggest the “Usim public” that is able to accept the usim card as payment. By installing it to public phone, both user and
telecommunications company will reach a effective way in order to maintain the public phone.
