What does one checkmark in an SMS in WhatsApp mean - briefly?

A single checkmark in a WhatsApp message indicates that the message has been successfully sent from your device but has not yet been delivered to the recipient's phone. This symbol appears after you press send and confirms the message is on its way.

What does one checkmark in an SMS in WhatsApp mean - in detail?

In the context of WhatsApp messaging, the appearance of a single checkmark next to a sent message holds significant importance in indicating the status of message delivery. When a user sends a message and it is successfully transmitted from their device to WhatsApp's servers, a grey checkmark will appear beside the message. This initial checkmark serves as confirmation that the message has left the sender's phone and is now in the process of being delivered to the recipient. It does not, however, guarantee that the recipient has received or viewed the message.

The single grey checkmark is crucial for users to understand that their message has begun its journey but has yet to reach its final destination. This status update helps manage expectations and provides a level of assurance that the communication process is underway. Once the message reaches the recipient's device, an additional checkmark will appear, turning both checkmarks blue, indicating successful delivery and receipt by the intended recipient.

In summary, the single grey checkmark in WhatsApp signifies that the message has been sent from the user's device and is currently being processed for delivery to the recipient.
