Mobile phones are slow to send and receive text messages. What is the reason and what should I do?

First, call the customer service and ask her to update the SMS data. It may also be a problem with the mobile phone system. If it has been upgraded, switch back to the original system or go to the mobile phone repair point to ask.

Mobile phones can't send text messages:

1. Your SMS center number is set incorrectly. For the center number, please consult the network operator (1860 or 100 10).

2, your mobile phone is in arrears, and the solution is to pay.

3. The SMS storage in the mobile phone is full, so it is impossible to save SMS or even information report. The solution is to delete the text messages that have been read.

4. In your mobile phone settings, there is one item, that is, SMS setting network selection. I think this is probably the reason for your mobile phone: automatically choose &; Only GPRS network &; Only applicable to GMS network, if you only choose GPRS network, you will not be able to send SMS. My classmate used to be such a reason. After my debugging, I can send text messages normally. Just try it.

5. The mobile phone can't send short messages. If the call is normal, it's not the card, but the information service center number in your mobile phone may have been deleted or changed, so you can't send text messages. The telephone number of the service center is +86 13800 (area code) 500 or you can ask the local mobile company yourself.
