Excuse me, what is the information center number of Chengdu Telecom mobile phone in the information settings?

Telecom uses CDMA network (C network for short), which is different from China Mobile Unicom, and there is no need to set the number of short message center. As long as the SMS function is turned on normally, it can be used without additional settings.

Number setting of SMS center in original GSM network (G network for short)

I. Introduction of SMS Center

Different from CtoC, sending SMS under G network needs to configure the correct SMS center number. China Telecom, Vodafone and Hutchison Whampoa are three cooperative nodes (SMS Gateway). The three SMS centers are located in Beijing, Shanghai and Guangzhou, and each node corresponds to a different province and city. Users in the corresponding provinces and cities need to set the SMS center to the number of the corresponding gateway before using it. Generally speaking, the business card manufacturer will embed the corresponding center number in the UIM card as required, but it does not rule out that the built-in information is incorrect due to unexpected circumstances. Therefore, when the user encounters the fault of sending short messages in CtoG state, it is necessary to guide the user to verify the number to ensure it is correct.

Second, the SMS center number

Guangzhou: Guangdong, Guangxi, Hainan, Hunan, Hubei, Henan, Yunnan, Guizhou, Tibet, Sichuan, Chongqing 1 1 provinces and Macao companies.

Beijing: Beijing, Heilongjiang, Jilin, Liaoning, Hebei, Shanxi, Inner Mongolia, Shaanxi, Gansu, Ningxia, Qinghai, Xinjiang, Tianjin and Shandong 14 provinces and cities.

Fourth, look at and change the way

Android phone can be viewed by typing *#*#4636#*#*. (SMSC project, some models can be directly modified by filling in numbers).

IPhone series can be viewed by pressing the call key after entering *#5005*7672# in the dialing interface, and can be modified by *5005*7672* SMS center number # call key in the dialing interface.

Some telecom custom machine, especially dual-mode mobile phones, have no short message center menu, so it can't be confirmed and modified intuitively.
