Why can't mobile phones send text messages but only receive them?

The SMS center number is wrong. Find the SMS settings, which should include the SMS center number.

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. 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. For your convenience, I list the numbers as follows: Beijing+861301kloc-0/2500 or 008613012500 Shanghai+86. 8+003 14500 Shenzhen +86 130 10888500 or 0086 130 10888500 Shandong+86130/kloc. +0500 Jiangsu+8613010341500 or 0086130/500 Zhejiang+861301036000 438+00380500 or 0086 130 10380500 Sichuan+86108113065438. 38+0500 or 008613010831500 Hainan+86130105015065438 or 0086/kloc-0. 8+030 10980500 Jilin+861301500 or 0086130109/kloc-0. 10 130500 Hebei +86 130 180500 or 0861301805438+0805438+0805500 Inner Mongolia+ Xi+8613010701500 or 008613010701500 Anhui+86130/kloc-. 306438 Xia +86 130 10796500 or 0086 130 10796500 Guizhou +86 130 1078500 or 0086. 438+030 10868500 Hunan +86 1073 1500 or 008613010731500 Hubei+86/kloc-. 5438+00500 Guangdong +86 130 10200500 or 0086 130 10200500 Guangxi+861301059/. 030 1076 1500 or 0086 1076 1500 Jiangxi +86 130 10720500 or 0086130. Edit a short message and send it to yourself, and check whether the setting of the short message center is correct. If you can receive it normally, you're done. This is also the easiest and quickest way to test the setting of SMS service center.
