What does the SMS center number in the mobile phone mean?

The SMS center number in your mobile phone is your SMS server. If it is not filled in correctly, the SMS cannot be sent successfully. Each region has its own information center number.

For example, the number of China Mobile SMS Service Center is++861380xxxxx500, where xxxx is your long-distance telephone area code. If it is less than 4 digits, it is 0. For example, my Wuhan is 027, that is 0270, which should be +86 13800270500, and if it is 0, it is 0.

After setting the SMS service center number, you can test it. Edit a short message and send it to yourself to check whether the SMS center is set correctly. If you can receive it normally, you're done.

The number setting method of SMS center is as follows:

1, open the phone address book on the phone desktop, any address book will do.

2. After opening the address book, enter "*#*#4636#*#*" in the quotation marks on the dial.

3. After entering, click the first "mobile phone information" that appears.

4. After entering the mobile phone information, slide the screen. At the bottom of the screen, there is a box that can be filled in. This mailbox is SMSC (short message service center), which is the information center.

5. Fill in "Update" in quotation marks, and then click "Refresh".

Generally speaking, the mobile phone will only change the number of the information center when it can't receive the information. For the number of information centers, different places are different, so we won't list them here. You can copy the content "xx center number query" in quotation marks, paste it into the browser, search, find the corresponding center number, and fill in the changes.
