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.
