Why does the mobile phone always show that it is sending text messages?

When you send a text message on your mobile phone, it shows that it is being sent for a long time. This situation has the following possibilities:

1, the first case is that this is normal, because the network signal is not very good, resulting in network delay. However, when using the mobile phone, after exiting the interface and re-entering, the display has actually been sent out.

In this case, press the sensing key on the right of Home and re-enter. At the same time, check whether the SMS can be sent and whether the flight mode is turned on. , just open it again.

2. There is another situation, which is caused by using mobile phone management software. Generally, there will be a startup prohibition item in mobile phone management software. After entering the software, check whether the short message is also banned. If it is banned, just change it and restart the phone.

At the same time, if it can't be solved, you can try to restore the factory settings, but remember to back up the data on your mobile phone with backup software.

3. In addition, the SMS function is turned off. This situation can be solved by telephone and manual service.

As short messages extend from mobile phones to PHS and fixed terminals, and from digital mobile communication networks to fixed telephone networks, only two things have not changed in this process:

First, the message length of short message is always less than 160 English or numeric characters or 70 Chinese characters, which is closely related to the mechanism of short message transmission based on the signaling network of communication system.

The second way is to send short messages-store and forward. When the user does not receive it, the short message will not be lost and will be temporarily stored in the short message center. When the user logs on to the network again, the short message will be quickly submitted to the user's mobile phone.
