Unable to receive the message sent by CNPC Hospital.

If it is a verification code, it is suggested to try sending and receiving again in another location to rule out whether it is caused by network reasons.

Change other time periods to receive again.

Verify whether the SMS blacklist function is set in the mobile phone: information-more-settings-blocked information-blacklist/whitelist/blocked phrase/blocked information-view (different mobile phones may operate slightly differently).

Check whether the mobile phone has downloaded the latest third-party software (security guards, system management). It is possible that the software intercepted the message. I suggest you try to uninstall it.

Try to replace another SIM card.

If not, please back up the telephone information (phone book, short message, multimedia information, etc.). ) and restore the phone factory settings.
