Besides sending short messages to operators, what other ways can telecom users check traffic?

There are many ways to do this. Personal suggestions can be queried by "traffic is coming", because it is also the AP P under the telecom, and the traffic can be queried later, and almost all the details can also be queried. Most importantly, it is an APP that provides users with free traffic, which is also quite good for those who lack traffic. I hope I can help you!
