Huawei p50pro has icon information in the upper left corner. What happened?

First, confirm the status of the SIM card to see if the telephone and Internet access functions are normal. If the call is limited and the internet is not normal, you can turn off the phone, unplug the SIM card and try to turn it on again.

If none of this happens, shut down and restart to clean up the mobile phone garbage, and there will be no more.

Some icon messages are reminders or received short messages do not affect normal use.
