It's actually quite simple.

I've had this problem before.

The sending phone number set in your phone has disappeared.

Just add it and you're good to go.

1. Check hard whether the number receiving the information is 11 digits, and there should be no spaces in the front, back and middle of the number.

2. Check whether the SMS center number is correct, if the number is wrong, the SMS cannot be sent successfully.

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

If your phone can't send text messages, you can try to test it back on or change your phone, and check if there are any of the following:

1.If the SMS number is set incorrectly, please re-enter the correct SMS number.

2.No signal or low phone battery;

3.If the system is busy during peak SMS sending periods during holidays, we recommend that you try again later or avoid peak sending periods.

4.The format of the sending is incorrect. If you send a text message to a PHS user, you need to add the area code before the number;

5.The SMS was sent for more than 24 hours;

6.The phone has blocked the SMS sending function;

7.Being blacklisted for SMS;

8.insufficient balance of numbers;

9.The SMS inbox and sending box are full.

If you are using an OPPO phone and cannot send text messages, please try the following methods:

1. What is the display below the SMS sent by confirmation? (SMS needs to be turned on in advance.)"Get a delivery report"function), if "sent" and "delivered" are judged to be the other party's problem, if it is "sent failed" or the status of the SMS cannot be known, it will enter the next step;

2. Check the SMS center number, first check whether the information center number of "SMS-SMS-SMS--Information Center Number Settings" in the mobile phone is correct (compare with similar local cards or consult the operator to confirm the message center number);

3. Check the receiving number, it is recommended to check whether the receiving number is correct? Whether to include special symbols such as commas, enter the number manually, remove special symbols;

4. Check network problems, if there is an abnormality in the use of individual places, there may be poor signal coverage areas and densely populated areas: leave the abnormal area for a certain distance, and restart the switch flight mode; If there is an abnormality in the use of all places, it is recommended to change the phone and change the card to confirm whether it is a problem with the mobile phone or the card, and contact the operator to deal with the problem of the card, and the problem of the mobile phone needs to be further sent to the official service center for testing.

First of all, you can check the 1st floor said about the arrears problem.

And is your location not covered by the network?

Secondly, you can check the SMS center in your mobile phone (in the "SMS" program, find the settings to view the SMS center), and if you don't have the number of the SMS center, you can't send and receive messages.

If you want to know the SMS center number of your mobile phone card, you can call customer service **10010 (Unicom), 10086 (mobile) to the manual desk to ask the SMS center number on the line The SMS center number is different in different regions.

The format is generally +8613***

And you can also go online to find it, but it is still recommended that you call customer service to transfer to a manual desk.

If that doesn't work, if you install software like Mobile Guard (which comes with your phone), you look at the permission settings of SMS (the app comes with it), and if you don't allow the app to send SMS, then you can't send it. It needs to be adjusted to Allow.

If it doesn't work anymore, I have to flash the machine to solve it. In general, this kind of problem is related to the permission setting, and the second is that the SMS center number is wrong.
