My mobile phone number is 133, and a classmate left me a message. Telecom sent a short message saying that it would call118114-0/. How can I listen to information?

Don't believe any news. Are you sure it's a telecom? Or the telecom number displayed by some scammers?

However,118114 is the best tone of China Telecom. Click, press 0 when you hear the prompt, and press 1 when you hear the prompt.

But I don't know the specific charge. Generally speaking, there is no need to listen to messages. There are indeed many liars. If the text message sent to you tells you which number to leave a message for, just call and say hello.
