To whom are messages sent when a phone number is changed in WhatsApp - in detail?
When a user changes their phone number in WhatsApp, the process of message delivery can be complex and involves several parties. Initially, all messages are still sent to the old phone number. However, WhatsApp uses its servers to intercept these messages before they reach the old device. Once intercepted, the servers reroute the messages to the new phone number associated with the user's account.
This process ensures that the user does not miss any important communications during the transition period. It is crucial to note that this redirection only works if the user has updated their contact information within WhatsApp before changing the phone number. If this step is skipped, messages may still be sent to the old number, and the user might lose access to some conversations.
In addition to rerouting messages, WhatsApp also informs contacts in the user's address book about the change. This notification helps ensure that all parties are aware of the new contact information and can update their records accordingly. The exact method of this notification varies depending on the device and settings used by each contact.
Overall, the seamless transition of message delivery when changing phone numbers in WhatsApp is a result of the platform's sophisticated server infrastructure and user-friendly features designed to maintain communication continuity.
