My mobile phone often receives fraudulent text messages and underground trading advertisements, and often hangs up as soon as it rings. What should I do?

Some illegal advertisers, through some illegal means, get everyone's mobile phone number and call you at a quiet time. They induce you to call back under the condition of ensuring that there are missed calls on your mobile phone, but you never have time to answer them. If you call back, you can hear a voice message similar to "XXX Notary Office reminds you that you have won the XX million prize" or "XXX Company sincerely welcomes you to buy XX products, which are of good quality and low price". Generally speaking, just hang up.

At present, China Mobile has not launched the service of shielding "this strange phone ringing". Users hang up when they encounter unfamiliar phone rings. Don't call back casually, be careful of the trap.

Reminder: Don't reply to strange numbers casually, you can send a text message to ask first. Adding a text message to the past can confirm that it is an advertising phone. You can call 10086 to complain about this number.
