Why can't my Lenovo mobile phone send text messages? A580 doesn't have a central number, so I can't send short messages with Unicom card.

There are several reasons why mobile phones can't send text messages:

1、? The SIM card of mobile phone is in arrears or stopped.

2、? The operator network is not normal.

3、? The short message is full, so it can't be sent or received (the phone prompt storage is full).

4、? The use of third-party communication software leads to compatibility problems.

5、? The instability of the system leads to the death of services and processes related to SMS sending and receiving.

6、? System abnormality or host hardware abnormality.

You can try the following troubleshooting methods:

1、? Verify whether the mobile phone card is down and whether the SMS prompt is full. (If yes, it is recommended to recharge; Clean up the text messages. Invalid next step)

2、? Restart the mobile phone test. (Objective: To solve the abnormal situation caused by the dead SMS process)

3、? Verify that third-party communication software is installed. (If yes, the notice does not rule out software compatibility. It is recommended to uninstall the third-party SMS software and try to use your own software. )

4、? Card replacement test (purpose: to eliminate operator network problems and SIM card compatibility problems)

5、? The backup data is restored to the factory settings, and the repair is invalid. (Goal: Eliminate system anomalies)

If the above operations can't solve the problem of the mobile phone, I suggest you send the mobile phone to Lenovo after-sales service station for testing and processing. What is the address of the after-sales service station/Lenovo/WSI/Station/ServiceStation/default.aspx? MIDH. or Lenovo service (music service)-service outlets for inquiries. The working hours of the site are generally 9:00- 18:00, and it is normal to go to work on weekends. All localities will make adjustments according to the actual operation. I suggest you call the site for consultation before you go. Please forgive me for the inconvenience!

Thank you for your support to Lenovo and wish you a happy life! ?
