What happened to my mobile phone? I don't know what happened to my mobile phone recently. A friend of mine never sends me messages. He can send it to others when he is out of town, but it always fails to send it to me. Occasionally, he succeeds, but I can get them from others. My mobile phone is made in China, and sometimes I can't get short messages with my smart phone. My ZTE mobile phone is like this, and so are other brands of smartphones of some friends around me. Below I will tell you how to solve it with my personal experience. 1. Most smart phones can be solved in this way, because all my friends' mobile phones are solved in this way, but I dare not say that all smart phones can be solved. It depends on what causes it, but you can try. 2. First, we turn on the dial and enter * # * # 4636 # * *, and the following screen will automatically appear: 3. In the above picture, we select "mobile phone information", and the following screen will appear: 4. Draw the screen above to set the preferred network type, and select GSMonly from the drop-down menu, as shown below: After setting, you should be able to receive short messages, which is how all the mobile phones I contact are solved.

2. China Unicom can't answer the phone and can't receive the short message.

1. Failure to receive SMS or verification code may lead to the following situations:

1, check whether the mailbox is full. If it is full, please delete some information;

2. If you still can't get it after deleting it, I suggest you change the machine or card to see if it is caused by hardware;

3. Check whether it is intercepted by mobile phone interception software;

4. Check whether the cell phone signal is normal and try to test whether it can be received in other places.

Second, the common reasons why mobile phones can't answer the phone and their solutions are as follows:

1, check whether the mobile phone is in arrears, and suggest paying for recharging;

2. Check whether the mobile phone is set with call forwarding, flight mode on and call barring. Suggest canceling and try again;

3. Check whether the function or signal of the mobile phone is normal. It is recommended to change your mobile phone or location and try again.

4. Try to restart or change the phone to see if you can answer the phone;

5. Bring the mobile phone card to the local business hall for testing or replacement.

3. What if Unicom's mobile phone can't receive the verification code?

The failure of sending and receiving short messages is generally caused by the wrong number of the information center, the arrears of the number, the abnormal reception and forwarding of the network base station, and the failure of the mobile phone. You can refer to the following methods to see if you can solve it:

1, consult the phone bill balance of the mobile phone card to see if there is any arrears;

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

3. Compare and observe the changes of SIM card and different time periods;

4. Try to restore the factory settings of the backup data (Settings-System "More"-Restore the factory settings, please do not check "Clear completely");

If the above methods fail to solve your problem, please take the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center for testing and handling.

4. Unicom's mobile phone number can't send and receive short messages. What happened?

Hello, first of all, I need to know if I can send a text message before. If you can send it before, the same number has not been upgraded or restored. Generally, there is something wrong with the SMS function. If you can't send text messages before, it may be related to the settings of your mobile phone.

Reasons for the failure of sending SMS by mobile phone:

1: The SMS center number is set incorrectly. Solution: Call the local Unicom customer service center (dial 100 10) and ask them to send you the number of your local Unicom SMS center. Then set it.

2. The mobile phone is in arrears. Solution: Charge the mobile phone in time.

3. The mobile phone is not in the service area. That is, the mobile phone is roaming, or the mobile phone is in the signal blind area. Some mobile phones can't roam automatically. Solution: Return to the cell phone signal service area in time. If the mobile phone can't roam automatically, handle roaming business in time before leaving the service area next time.

Doing business is free. Only roaming charges will be charged if you use it when roaming. Of course, roaming charges will only be charged for calling, and roaming charges will not be charged for texting and surfing the Internet.
