WhatsApp, owned by Meta, has introduced a new feature that simplifies messaging for users who want to chat with people not saved in their contact list. Previously, users had to use third-party apps or go through various steps to message unsaved numbers, causing inconvenience for quick conversations. Now, users can start a new chat on WhatsApp, enter the unknown number in the search bar, and a Chat button will appear, allowing them to initiate a conversation without the need to save the number in their phone. This feature is available on the latest builds of WhatsApp for both iPhone and Android devices, as reported by WABetaInfo. Moreover, WhatsApp is reportedly working on @username support, making it even easier to chat with new contacts without knowing their phone number. To access this feature, users should ensure they have the latest build from the Play Store, as it might take some time for the feature to appear due to a server-side rollout by Meta.
