According to WhatsApp, anyone who still hasn’t accepted their new terms of service, ie, WhatsApp “update”, will first be sent persistent reminders to accept the new terms to use the app. While there is no specific window mentioned for the duration these persistent reminders would last or how persistent they would be, WhatsApp says that if you still don’t accept, there will be consequences. Till you accept. First, your access to the chat list within WhatsApp will be restricted, which means you won’t be able to see messages in what is essentially an instant messaging app. If you have notifications enabled on your phone, you’ll be able to see incoming messages in the notification itself and reply from there. You’ll be able to answer incoming WhatsApp voice and video calls for the time being. Eventually that’ll also stop.
“After a few weeks of limited functionality, you won’t be able to receive incoming calls or notifications and WhatsApp will stop sending messages and calls to your phone,” says WhatsApp. There is no specific time frame mentioned for what the ‘few weeks’ would be.
