What is the reason why the short message on the mobile phone cannot be sent?

1. The easiest, use the "Factory Reset" function in the phone settings, and follow the prompts

2. Enter * - soft reset of the mobile phone (save ** number, information, incoming and outgoing caller numbers, etc.) after the grid

3. Enter *, the original password is 12345. Will your phone prompt you to restore all factory settings? The phone will restart, select Yes, and then enter the lock code, the default is 12345, and select Confirm after entering.

It should be noted that there are some e-disk software (such as call enhancement, screen saver, etc.) that boot and start the permanent memory, as well as Q9 and T9 fonts, and if the font is running, it is invalid to format it with this method. Therefore, before the soft grid, close all these software, and delete the Chinese font file before the format can be successful. Font files are generally under system fonts, please change the name to the fonts directory to delete the font file, and then delete!

Hard-grid machine. This method is generally used when the system is so chaotic that it cannot be turned on

Turn off, press and hold the call key when you turn on the 3rd key * key and then press the power on button Don't let go =, and then, start formatting.

This formatting is more thorough and does not cause invalid formatting.

Other: Turn off and press the power button, without any prompt to start the grid

Precautions: Sufficient power must be guaranteed when formatting, and generally it should be operated under full power.

It's a good idea to uninstall all the software and see if there are any similar "system errors"! If there is no similar "system error", then proceed to the grid! Do not attempt to shut down the machine during the grid, do not plug in the charger, etc. Also, try to give priority to the soft grid.

The software part that was originally installed on the MMC card will be affected after the grid machine, so under normal circumstances, the important data of the MMC card will be backed up and then formatted, and all the programs saved in the E disk will be reinstalled after the formatting of the mobile phone is completed

In short, the most thorough formatting steps are: uninstall all the programs that can be uninstalled in the program management Remove the MMC card Check if there is a system error Format the phone Install the MMC card Format the MMC card (the phone at this time is the purest basic system) Install the programs that need to be installed Restore contacts is completed

Message Center** is not true.

The center number of the SMS is incorrect.

The network is not good, and we are also during this time.

2. If the mobile phone is not in arrears, check whether the airplane mode is turned on, and turn off the airplane mode;

3. Communication problems, which may be caused by bad signals or communication errors.

None of the questions asked.

I don't know what's going on.

If you want to answer the mobile phone question, first enter the mobile phone SMS settings to see if there is a problem with the SMS center number, you can call the operator's customer service to ask the local SMS center number, or you can check it online. Generally, if you still can't send text messages after setting it up, it should be that there is a problem with your phone's SMS app.

4. If the problem persists, try a factory reset.

5. If the problem still cannot be solved, please take the mobile phone to the after-sales service for inspection and repair.

2. The number of the information center of the mobile phone is set incorrectly, which does not conform to the actual information center number of the province.

Don't be in a hurry, it may be that we accidentally turned on the airplane mode. Start by opening the settings and turn off airplane mode. If it's not because of airplane mode, then open the message and check whether the number in the sending and receiving is correct, if it doesn't work, you can try to check whether the phone is in arrears.

There are many reasons why the mobile phone SMS cannot be sent, such as too many short messages, mobile phone failures, arrears, and non-existent sending numbers.

The failure to send text messages on the mobile phone may be a sign of a malfunction of the mobile phone, or it may be that there are too many short messages. You can consider deleting some of them and trying again.

See if there is arrears, whether you can send it out, and it is generally in arrears that you will be restricted from use.

The mobile phone text message cannot be sent, there is no network, and the mobile phone may be broken.

Is there a problem with the SMS center number setting?

1.The other party has set up a firewall, and your text message has been successfully sent, but the other person's mobile phone refuses to receive it. The billing is still the same, and the delivery is successful, but the receipt received is a failure.

2.The other party's mobile phone is turned off, or there is no signal, and the other party does not receive the SMS you sent, but if the time exceeds the validity period of the SMS set by the other party, it will also prompt that the sending is successful, but the receipt received is a failure.

3.Communication problems, that is, they have nothing to do with the mobile phones of both parties, may be caused by a bad signal or a communication error.

Secondly, as long as your phone shows that the sending was successful, it will be billed. It doesn't matter if the other party receives it or not. That is, if you send an SMS to a down number, you will be charged as long as it is successfully sent.

Under normal circumstances, the communication situation is not good, you can go to a place with a strong signal and send a text message.

Asking questions is either a question or a failure as soon as the message is sent.

Question: No. I can't send it to 12306.

Ask a question, oh, I'll try.

It's also possible. 1.If the mobile phone is shut down in arrears, it is natural that you can't send short messages. 2.

The text messaging feature is banned, which means that after you send four text messages, the feature is banned. You can consult customer service to reactivate the function. 3.

If the SMS center number is incorrect, consult customer service and correct the SMS center number. 4.The wrong number was sent.

It may also be that after sending some text messages, they were banned by the carrier. Reactivation can be requested.

If you can't send SMS messages, either you owe money, or there is something wrong with your phone settings.

Check whether the phone is in arrears, whether the phone has a signal, and whether the phone has set the offline mode.

The phone can't send text messages to check if there are any of the following:

1. Whether the SMS center number is set correctly, please enter the correct SMS center number;

2. No signal or insufficient mobile phone battery;

3. The system is busy during the peak period of sending SMS messages during holidays, so it is recommended that you try again later or avoid the peak sending period.

4. The sending time of the SMS exceeds 24 hours;

Fifth, the mobile phone has blocked the SMS sending function;

6. The other party's number is included in the SMS blacklist;

7. The balance of the number is insufficient;

8. The SMS inbox and sending box are full.

It should be a problem with your phone's settings.

Turn it off and restart your phone.

Whether there is no signal or no effective receiver.

The inability to send text messages on mobile phones is generally caused by the lack of network.

See if your phone is in arrears.

1.Open the settings for SMS on your phone.

2.Find the dashboard in the SMS settings.
