What does one white checkmark in WhatsApp mean - in detail?

The appearance of a single white checkmark on WhatsApp indicates that your message has been successfully sent from your device but has not yet been delivered to the recipient's phone. This status symbol is part of WhatsApp's messaging system, designed to provide users with real-time updates on the delivery status of their messages. When you see this single checkmark, it means that the message has left your phone and is currently in transit through WhatsApp’s servers to reach the intended recipient. However, until a second checkmark appears (either gray or blue), the message remains undelivered. If any issues arise during transmission, such as network problems or the recipient's phone being offline, the single white checkmark will persist until the message is successfully delivered or fails to reach its destination. This feature helps users monitor the progress of their messages and ensures they are aware of any potential delivery delays.
