Beginners receive questions about mobile phone cards, please help me to answer them.

1, hello, friend. First of all, don't use this card, but don't throw it away. When you get to school, you can consult freshmen, find other students to see the specific tariffs or other uses, and see if others have used them.

2. If it really doesn't fit, you can buy a new card near the school, a stall or a small business hall, or you can buy an old one. Look carefully before you buy it. Beware of being fooled. Freshmen have just arrived. Don't worry. Get familiar with the environment first and take your time.
