Android phone can't send text messages, but it always shows that it is sending, but it can receive messages and make phone calls to solve problems.

The main reasons and solutions are as follows:

1. It is recommended to confirm whether the mobile phone is in arrears first. If you owe money, please pay the operator and try again.

2. Please confirm whether the SMS can't be sent to all contacts normally. If it is a personal contact, it is suggested to recall whether the relevant contact blacklist has been set, or use some third-party SMS to intercept relevant functional software.

3. Rule out the above possibilities, or it may be caused by an abnormal SMS program, and "clear the data" to improve. Please back up SMS, contacts and other information before operation to avoid data loss.

4. If possible, it is recommended to replace other SIM cards to see if you can send short messages normally. Do not rule out that it is caused by the abnormality of your SIM card.

5. It cannot be improved after the above operations. It is recommended to back up the fuselage data and restore the factory settings to see if it can be improved.

The problem still cannot be effectively solved. For the normal use in the future, it is recommended to go to an authorized maintenance station nearby for specific inspection and treatment to see if the function of "automatic startup disabled information" is turned on.

Extended data

Cleaning the data will enable the mobile phone to send short messages, and it can also have the following benefits:

1, with more cache and data accumulation, the running speed of the mobile phone will slow down. Understanding these can effectively make the system smoother and release more system memory.

2. The cache generated by mobile phone software will be opened faster next time, and it is not necessary to clean the cache frequently.
