I send bank card information with short sleeves, and then I can't send text messages.

What you want to ask is the reason why the text message can't be sent out The specific operation is as follows:

1. Inquire whether the SMS function of the mobile phone card is turned on normally; (You can test whether you can receive the short message, and if so, it means that the short message function is normal. )

2. Check whether the number of the SMS center is correct; (How to set the number of China Mobile SMS Center: Enter Message-Settings-More Message Settings-SMS Information Center Settings. The number of China Mobile SMS Center is +86 1380ABCD500, and ABCD is the local area code. If the area code is three digits, the last digit should be 0. (Example: Shanghai 02 1, and the number of SMS center is+8613800210500; Zhengzhou, Henan 037 1, SMS center number +86 1380037 1500).
