What is the problem that Lenovo a378t mobile phone always displays information without sending it?

Lenovo A378t mobile phone short message display is not sent, so it cannot be sent normally. Refer to the following troubleshooting steps:

1. It is recommended to confirm whether the mobile phone is in arrears first. If it is arrears, make up the fee with the operator and try again.

2. Reconfirm whether the SMS cannot be sent to all contacts normally. If it is a personal contact, it is suggested to recall whether the relevant contact blacklist is set, or use some third-party SMS to intercept relevant functional software;

3. Rule out the above possibility, or it may be caused by an abnormal SMS program. You can download other third short message software for comparison, or improve it by entering System Settings-Application Management-Finding the corresponding short message-"Clear Data", and back up short messages, contacts and other materials before operation to avoid data loss;

4. If possible, it is recommended to replace other SIM cards to see if you can send short messages normally. Do not rule out that it is caused by the abnormality of your SIM card;

5. It can't be improved after the above operations, so it is recommended to back up the fuselage data and restore the factory settings.

If the problem still cannot be effectively solved, it is suggested to take time to go to a nearby Lenovo authorized repair station for specific inspection and treatment.
