China Petroleum Hospitality Apple mobile phone cannot enter the verification code.

It is suggested to change to another location and try to send and receive again to rule out whether it is caused by network reasons.

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. Check whether the SMS center number is correct. If the problem still exists, please contact the local manual customer service for further processing.
