4G really consumes a lot of traffic, but why should we surf the Internet during class? At best, I just don't want to buy cardboard textbooks. Look at the next electronic PDF in class. I surf the web on the 4G network every month and QQ doesn't watch videos. The 30 yuan/month package is really not cost-effective. If you just want to use it in class, there is really no need to buy 4G. Besides, the ipad is really not suitable for studying ... It's better to add some money to buy a better laptop.
