What's wrong with the mobile phone prompting to send a short message to a certain number?

Because there is a short message receipt in the mobile phone service, it is also feeding back the reception of the other party. When the receipt prompt is: sending failed, there are the following possibilities:

1, the other party shuts down.

2. Without the signal, the other party can't receive it.

The other party blocked your number and could not receive it.

4. Network traffic jam. In either case, I suggest you send it again after a while, which is generally no problem.

About the trap of mobile phone short message

At present, some consumers often receive some inexplicable short messages, which make them uncomfortable and even suffer losses. Most of these short messages are fraudulent short messages sent by criminals taking advantage of people's possible carelessness. Consumers should be highly vigilant. According to the actual situation of consumers, SMS fraud can generally be divided into the following categories:

First, "pretending to be customer service" swindles money.

Two, to sell low-priced smuggled goods as bait to defraud money. Taking advantage of the psychology that a few people may love cheapness, they lied through short messages that there are various cheap smuggled goods such as cars, computers and mobile phones confiscated by the customs for sale, and they can order them by mail at low prices. After you pay the deposit or consignment fee, they steal your credit card number and password on the grounds of checking the buyer's credit strength, and finally withdraw your deposit with a forged credit card.

Third, induce you to call back and "cheat" the phone bill.

Fourth, low-interest loans are attractive. Send SMS in the name of "handling low-interest unsecured loan business". When you reply to the other party, the other party will often ask you to deposit a certain amount of cash in the designated account as interest paid in advance. When you deposit interest and ask the other party to cash the loan, the other party may ask you to continue to pay back the money for other reasons or it has disappeared.

5. "Remittance emergency" type.

Six, to provide prizes and bonuses as bait to defraud money.

Seven, the temptation of victory. One day, I suddenly received a short message informing me of the first prize of what project I won. The reward was very attractive, but I obviously didn't participate in this project or activity. Then, there is no doubt that it must be a scam message. The purpose of a liar is to attract you with extremely high profits, let you fall into the trap, and then let you pay some money in advance.
