Xiaomi 12pro can't receive SMS with 4G card.

If you use your mobile phone abroad or if you can't receive SMS when you use your mobile phone abroad, it is suggested that you can try to get it later if the signal network is delayed.

Turn off and restart Xiaomi's mobile phone, check whether the mobile phone can receive short messages normally, call the service number of the mobile communication service provider, and check whether the short message service is out of order.
