What if the mobile phone can't receive the service information?

1. Make a phone call and try to rule out whether it is caused by the arrears of mobile phones.

2. Check whether all the short messages are not received. If individual or partial numbers cannot be received, please check whether the information interception function (such as SMS blacklist) is set.

3. If the prompt shows that the memory is full, please optimize the memory of the mobile phone (for example, delete some short messages).

4. If it doesn't work, please turn off the phone, take out the SIM card and try to insert it again.

5. Update mobile phone system version: Settings-(about mobile phone/system update)-Manual download update/automatic download update (software update/system update-update). Note: Please back up the data in the device before upgrading.

If it still doesn't work, you can check your mobile phone and see if you can receive ordinary text messages. If you receive it normally, it is recommended to call the service desk and ask him to help you brush the message. If not, see if the information center in the information settings has changed.
