First, in order to facilitate the contact between students, they will change to the local card where the university is located after entering the university. Telephone cards (including telephone charges and package fees) are purchased by the university and distributed to each student together with the admission notice.
Second, after students come to the university, there will be a designated activation place for students to activate their calling cards. Generally no one keeps the original number. You can open packages such as family happiness when you call home, and services similar to city roaming packages can be opened when you go home on holiday.
