What's the matter with the mobile phone information not being sent out?

1. Signal problem: When the cell phone signal is unstable or in a no-signal area, the information transmission may fail. Try to move to a place with a good signal before sending it.

2. Account problem: If the balance of the account bound by the mobile phone is insufficient or there is arrears, the information transmission will also fail. Check the account balance or contact the operator to find out about the account.

3. Operator problem: Sometimes the operator's network may fail or be under maintenance, resulting in the failure of information transmission. You can contact the operator's customer service to understand the specific situation.

4. Mobile phone settings: Mobile phone settings may affect information transmission. For example, if the flight mode of the mobile phone is turned on or the number of the SMS center is set incorrectly, the message sending will fail. Check the phone settings to make sure they are configured correctly.
