Telecom charges 30 yuan. The message is true.

First, a liar

Process: After paying the money, you will receive a short message, which is sent to you through other ports (such as 10657), and the content is probably that the recharge was successful.

Identification method: Call 10086 immediately, and the results can't be found through the mobile company system query.

Reminder: Don't be greedy and don't be fooled.

Second, the callback card

Process: After payment, they will tell you how to use it. I want you to dial a specific number first, and then dial the phone number you want to dial.

Reminder: This callback card is an illegal operation mode by taking advantage of the loopholes in the telecom company. The money you paid will be gone at any time, and you can't find them. Not recommended

Nothing for nothing. Be vigilant and don't be greedy.
