No, unless the mobile company signs an agreement with the university. Generally speaking, the university's admission notice will include the university's local calling card for students to use when they go to school. Look at the companies that sign contracts with schools, some are Unicom cards and some are telecom cards. If necessary, you can use the calling card issued by the school directly. This is a real-name registration business card printing, with a student ID card, so you can use it with confidence. The packaging inside is generally more favorable. If you don't want to change your original calling card, the card issued by the school doesn't need to be activated.
