Can SMS be opened?

Do not open SMS, only set the number of SMS service center. If you want to send MMS, you should open GPRS to the network operator for free, and then make the necessary settings for the mobile phone before sending it. If you want to send and receive text messages on your mobile phone, you must set it in your mobile phone. The most important task in the setting process is to fill in the correct SMS service center number in the relevant options of the mobile phone. Setting the number of SMS service center is the technical preparation for sending and receiving SMS. This work is one-off, and there is no need to repeat it after completion. At present, the mobile communication operators in Chinese mainland are China Mobile and China Unicom, so there are two ways to set the number of SMS service center. First, how to set up the SMS service center of China Mobile. China mobile short message service center, the number is+861380xxxxx500, where xxxx is the long-distance telephone area code of your area. If it is less than 4 digits, it is 0. For example, Wuhan where I am located is 027, that is 0270, and Shanghai should be +86 13800270500. 0 is 02 10, so it should be +86 138002 10500. By the way, the long-distance area code used for the number of China Mobile SMS Service Center is the long-distance area code of China Telecom, which just shows that China Mobile was spun off from the original China Telecom, so it can be seen that it used to be a family. Second, the setting method of China Unicom SMS service center Before using SMS function, you should first confirm whether Unicom in your area has opened SMS service. Please contact local customer service 100 1 for details. For China Unicom, the SMS service center number of Unicom is not like that of China Mobile, and the rules are complicated, so it can only be obtained by looking up the table.
