What's wrong with texting

Sending information failed, which may be caused by signal problem at first. Suggest users to resend it, or try sending again after turning off and restarting the mobile phone. Secondly, turn on the dialing function in the mobile phone, then enter *#5005*7672#, click Dial, you can see the number of the SMS center, return to the dialing interface, enter *5005*7672* SMS center number, and click Dial to set the number of the SMS center. After the setting is successful, check whether the SMS function can be used normally. Maybe the mobile phone card is in arrears. Call the operator to check the remaining phone bill, or plug the phone into other equipment to try to receive SMS. Check whether the mobile phone is the latest version of the system. If it is an old version, it is recommended to upgrade to the latest version. If it is a system BUG, the updated version will be fixed.
