As a general rule, yes. If you’re a student at a Chinese university, generally during the big day of registration and enrollment one of the services provided for freshmen is the activation of a telephone line with cell and internet service included. This is often at very favorable rates. In fact it’s possible to save a few hundred RMB by activating internet service at this time rather than going to official stores, or even worse, the disreputable little shops that sell everything. Moreover, if you already possess a telephone line and just need to add internet service to your cell phone, this is the right time to make a simple integration. It’s easy, fast and convenient!
But always be on guard for scams!
