Why can't I get the verification code on campus?

If you can't receive the SMS, contact the operator.

Users often ask that mobile phones can't receive short messages, or that short messages will be delayed. In fact, mobile phones can't receive information. Generally speaking, it has little to do with their own hardware, and most of them should be caused by software. Wrong number of SMS center: The corresponding SMS center number is different due to different regions of the country and different operator networks. In addition, for users, it is not only tedious to find the number of SMS center on the Internet, but also the version and year of many materials will cause inaccurate information. Here I suggest you go to the local operator's business hall to find out, or call to ask.

Poor cell phone signal leads to network instability: if you are in an unstable situation, the network is temporarily missing, or affected by other aspects, SMS may be temporarily unavailable or delayed. To solve this problem, you need to go to a place with good signal to receive short messages. Many users also ask that there is a message icon flashing on the top of the mobile phone, and I don't know what it means. This is to remind you to clear your inbox in time. The same is true for ordinary text messages. In addition, many users also have the habit of retaining information. Many a mickle makes a mickle, which will inevitably lead to the flood of information and make it impossible to receive new information. So users in this situation need to clean up their mailboxes in time.
