How does telecom check traffic through SMS?

1. You can directly edit the unified traffic query code 108 1 and send it to 1000 1 to query your own traffic usage.

2. You can also dial China Telecom's self-service hotline 1000 1 to connect, and press the corresponding number keys according to the voice prompts to check your traffic usage.

3. You can also download China Telecom's Pocket Business Hall directly, and then log in your mobile phone number, so you can see your traffic surplus and phone bill usage on the home page.
