If the store is not connected to the internet and needs to be pushed, how can I inform the guests?

If the store is not connected to the internet and needs to be pushed, you can notify the guests by text message or phone.

Web page push means to quickly forward the sorted information resources to the user's interface in the form of web pages, so as to realize the multi-level needs of users, so that users can set their own information channels and receive customized information directly at the user's end. The push scheme should support transparent transmission and various encryption schemes to ensure the security of information transmission. The ID system of the push scheme should be independent of the ID system of the existing website or service, so as to ensure the accuracy of information delivery after users log in on different mobile phones and avoid the wrong delivery of information caused by network transmission due to the failure of unbinding events.
