Why does sending a question fail, and why does answering a question always fail to send?

Because the question you asked is so yellow or cult-like.

1. Some SMS messages cannot be sent

1. If the SMS contains sensitive words, the other party cannot receive it after sending it.

Please use the test statement to send an SMS message to confirm whether the other party can receive it normally, such as sending: thank you, etc. If the other party can receive it normally, it means that the previously sent SMS may contain sensitive words.

2. Check whether it has been turned on"Fixed dialing"Business.

After fixed dialing is enabled, you can only send messages to contacts in the fixed loser dialing list, and cannot send messages to other numbers. If you want to continue sending SMS, cancel the fixed dialing service. Go to Settings - Application and Permissions - System Application Settings - ** - Mobile Unicom Telecom - Fixed Dialing, turn off Fixed Dialing (the pin2 code that needs to be entered when closing needs to consult the operator).

3. It is not possible to send SMS to certain short numbers.

2. All text messages cannot be sent

It may be because you don't have an SMS center number set up.

The SMS center number is different from place to place, first of all, you need to know the principle of sending SMS. To put it simply: you make up the text message and send it to the switch, and then send the text message to the other party's mobile phone through the switch.

When the SMS gateway is reached, there is a process of judging the caller's attribution, and the mobile phone with the center number will also send the signaling of the center number to the SMS gateway when the SMS is not sent, so that it can be sent normally.

The format of the mobile SMS center number is: +8613800 region** (if Chengdu is 028, write 280, the first digit of the four-digit area code has 0 omitted, and the three-digit area code writes 0 behind), and finally 500It's all +8613800280500.

When sending a text message, it shows that it is being sent, and after a while, it is a sending failure, what is the matter?

2. After opening the book, you will see the number of the information center, which is a string of numbers to +8613800 area code 500, click to confirm.

3. Then click Resend on the text message that failed to send.

4. After changing the correct message center number, the SMS can be sent immediately.

The network is not good.,It's the most likely.,Or it's just the phone card.,It's good to log out and log in.,If it's not good, you can uninstall it and reinstall it.。 Hope it solves your problem.
