Xiaomi 1 1 Card 1 Cannot send SMS after 5g is turned on.

There should be no 5G base station in this location.

First of all, it depends on which operator you belong to, China Mobile, China Unicom or China Telecom. You can call the operator directly, and people ask for manual service to see if there are any restrictions on the SMS function. If the short message function is limited, it can be solved by asking to reopen the manual service and restart the mobile phone.

You can't get the message. Maybe your card is broken, or there is something wrong with your mobile phone. You can go to the office and ask the salesman to reinstall the card on another mobile phone. If you can get the text message, there may be something wrong with your mobile phone.
