How to cancel Huawei's SMS reminder twice?

1. It may be caused by a system failure, not a problem with the mobile phone system at all. It may be that a friend's mobile phone SMS notification has been set several times, so let the other party set-notification-SMS-repeated reminder at the bottom, and choose to remind once. You can check the short message bill to see how many short messages the mobile phone sent to this number. If there is only one, it is obviously a problem with a friend's mobile phone or related telecommunications service system. And if you send too much, you can look at the relevant settings of your mobile phone or consult the relevant telecom service provider.
