The new iOS version makes it easier for customers to manage all of their chats in a single app, but on Android, accessing two accounts at once requires a dual SIM configuration.
By keeping account information distinct, this functionality will enable users to manage discussions from several accounts inside a single app. Each account's settings, conversations, backups, and notifications will continue to operate independently. Because they won't have to link each SIM to a different instance of WhatsApp or WhatsApp Business, users with two SIM cards will profit. Rather, the main program will handle both numbers at the same time with ease.
