Why does Lenovo a656 take a long time to send short messages, and the traffic can't be used, but the mobile phone can be used normally?

Dear users, thank you for choosing Lenovo products.

I am very sorry for the inconvenience caused to your use.

If you find that the traffic is not available online, please slide down the notification bar at the top of the screen and click the data link.

If you can't connect to the Internet normally after turning on the data connection function, please refer to the following suggestions:

1.A656 currently supports the data connection function of mobile and Unicom cards. Please make sure that the sim card you are using is within this range, and the phone is not in arrears.

Please make sure the surrounding network environment is good. You can change the use environment or compare it with other users nearby, and try to turn off WIFI first.

You can try to change the sim card to another mobile phone if you can. If there is a problem with other mobile phones, it is not excluded that the sim card is abnormal. It is recommended to contact the operator for further processing.

4. Please go to: System Settings-More-Mobile Network-Access Point Name, switch the existing access point and restart the observation;

5. Have you ever recalled whether the Internet access function was restricted by Le Security or other software? If so, cancel the restriction;

6. Please back up the fuselage data and restore the factory settings (password is 1234). If it is ineffective after recycling, please send it to the maintenance site for treatment in time.

If the SMS takes a long time to send, we suggest that you refer to the following methods:

1. Near the rush hour, too many users may visit the base station, which is caused by the network congestion of operators. I suggest you try to change the time period and environment, or call the operator to find out the situation (mobile customer service:10086; Unicom customer service:10010; Telecom customer service: 10000)

2. Excluding the above possibilities, it may also be caused by abnormal SMS program settings. I suggest you enter the information interface, click the menu button-Settings-Restore the default settings, and observe the attempt;

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

4. It cannot be improved after the above operations. It is recommended that you back up the fuselage data and restore the factory settings.

If there is still obvious delay abnormality after the factory settings are restored, it is recommended that you contact the maintenance station for specific detection and treatment.

The address of the maintenance station can be found in official website:

I hope the above information can bring you some help, thank you for your support to Lenovo, and wish you a happy life!
