Can I modify the number for receiving Phone/Message notifications? Is the phone number for call/SMS notification fixed?

1. Phone notification: After purchasing this service, every time the notification is triggered, we will make one phone call to the number you added .
2. Message notification: After purchasing this service, each time the notification is triggered, we will send 1 SMS to the number you added.
3. After you subscribe to the service, you can go to the "Smart--Phone Notification" page and click the "Set Recipient " button to add/delete phone numbers for receiving notifications (the mobile phone number bound to your App account cannot be deleted).

Note: the phone number notified by the call/SMS is a service number segment provided by the telecommunications service provider, so the phone number is not fixed, but constantly changes within a number segment.
