If I change my phone number will WhatsApp still work - briefly?
If you change your phone number, WhatsApp will stop working on the old number but will continue to function normally on your new number after you complete the transfer process within the app.
If I change my phone number will WhatsApp still work - in detail?
If you change your phone number, WhatsApp will continue to function for incoming messages, but there are several important aspects to consider.
Firstly, it's crucial to understand that WhatsApp uses your phone number as your unique identifier within the app. This means that when someone sends you a message, they do so using your phone number. If you change your phone number without informing your contacts, they will continue to send messages to your old number, which you won't be able to receive.
Secondly, WhatsApp does not provide an official feature to change your phone number directly within the app. However, you can manually update your number by creating a new account with your new phone number and then deleting the old account. It's important to note that this process will result in the loss of all your chat history and media associated with your old number.
Additionally, if you decide to keep both numbers active (for example, using one SIM card for WhatsApp and another for calls), you can register both numbers with WhatsApp. This way, you can receive messages on both numbers. However, this approach requires having a dual-SIM phone or using an additional device.
Lastly, it's essential to inform your contacts about the change in your phone number as soon as possible. This ensures that they can update their contact lists and continue communicating with you without any interruptions.
In summary, while WhatsApp will still work after changing your phone number, there are significant considerations regarding message delivery, chat history, and informing your contacts.
