What's the number of the information center? Under what circumstances should it be changed?

The information center number is your SMS server. If you fill in the wrong number, the message can't be sent successfully. Each region has its own information center number. Many mobile phones produced now do not need to be input by themselves. If you are not clear, you can ask the local network operators, China Mobile/KOOC-0/0086, China Unicom/KOOC-0/0/KOOC-0/,PHS/KOOC-0/0060.

The number of China Mobile SMS Center is +86 1380 * * * 500, where * * * is the local long-distance area code. If the area code is less than 4 digits, it is filled with 0.

For example, the information center number of Beijing Mobile (0 10) is +86 13800 100500, and that of Shenzhen Mobile (0755) is +86 1380075500.

China Unicom's SMS center number is +86 130 10***500, but * * * is irregular. The number of the SMS center of China Unicom is listed below.

Under normal circumstances, the phone will default according to the SIM card used. If manual adjustment is needed, it should be selected according to mobile and Unicom.
