Method As soon as you enter the settings or click on the newsletter directly, you will find your own information center number at the bottom after entering the settings. Generally speaking, you can change the correct information center number by clicking this center number. You can copy the content "xx center number query" in quotation marks, paste it in the browser, search, find the corresponding information center number, and fill in the changes. If you can't change it here, please see method 2.
Method 2: Enter the dialing interface, enter the content "*#*#4636#*#*" in quotation marks on the dialing keyboard, and then click the first "mobile phone information" that appears. After entering the 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. Fill in the quotation marks "Update" and click "Refresh".
Note: Generally speaking, mobile phones can't send and receive messages before changing the number of the information center. The number of the information center varies from place to place, so I won't list them here. You can copy the contents in the quotation mark "xx center number query", post it to the browser, search, find the corresponding center number, and fill in the modification.
Mobile phones can make calls and receive messages, but they can't send messages. What happened? Did you delete the number of the information center? If you can set it yourself, set it yourself. If you can't, call customer service.
