Why can't oppo receive SMS?

It is suggested to try according to the following scheme:

If the contact is not blacklisted or blocked, you can't receive messages from individual contacts. It may be related to the other party's mobile phone or network. Your mobile phone is fine, please rest assured.

It is recommended to compare other mobile phones to see if they can receive the verification code normally. If other mobile phones can't receive the verification code, it may be a service problem of a third-party application, so you can contact the software for feedback. If other phones can receive the verification code, you can try to uninstall and reinstall the software (application data will be lost). After restarting the phone, see if it can be restored. If it still can't be recovered, it is recommended to go to the service center for testing.

You can turn off functions such as harassment interception/blacklist/information interception, and try to receive the verification code.

Areas with poor signal coverage and densely populated areas: restart/switch flight modes at a certain distance from abnormal areas; If affected by the environment, there may be poor signal or network congestion. It is suggested to try to leave the area for a certain distance, then restart the phone or switch flight modes to see if the problem can be solved.

Comparative test of changing machine and card. If it is determined that it is a card problem, it is recommended to contact the operator for handling; If there is a problem with the mobile phone, it is recommended to back up important information in advance (such as WeChat chat record: WeChat-I-Settings-Chat-Chat record backup and migration), and then take the purchase voucher to the nearest service center for testing and processing. You can call the service center in advance to consult the working hours and related information to avoid running empty.
