Why can't Shandong Telecom's mobile phone receive the SMS from the Traffic Management Office?

Possible reasons: 1. Interception software is installed on the mobile phone. 2. The mobile phone is turned off, there is no signal for the time being, and it is overdue or stopped. 3. The first day of recharging after the mobile phone is in arrears. 4. The user has set a blacklist on the operator side. 5. The mobile phone can't receive short messages of more than 70 words. 6. Mobile phones are used abroad or overseas mobile phones are used. 7. The message is full. 8. Mobile phone networks and operators have failed in some areas. 9. Mobile phone system failure. Solution: 1 Remove the SMS interception of the application software, or change the mobile phone. 2. Arrears for downtime are generally within 24 hours after payment, basically within 24 hours. I suggest you change your mobile phone number or pick it up the next day. 3. Contact the operator to cancel the blacklist. 4. If it is a signal network delay, you can try to get it later. 5. Check whether the mobile phone is root/ jailbreak or refresh, and change the mobile phone system back to the official standard version.
