When you send a message on WhatsApp and see one check mark, it means that your message has been sent from your device but has not yet been delivered to the recipient's phone.
If there is one check mark when sending in WhatsApp, what does it mean - in detail?
When you send a message on WhatsApp and see a single check mark next to it, this indicates that your message has been successfully sent from your device but has not yet been delivered to the recipient's phone. This means the message is still in transit and has not reached the recipient's device.
The single check mark serves as an initial confirmation that WhatsApp has processed your message and forwarded it through its servers. However, it does not guarantee that the recipient has received or seen the message yet. Once the message reaches the recipient’s phone, even if it is not opened, you will see two gray check marks indicating delivery. If the recipient reads your message, the check marks will turn blue.
In summary, a single check mark on WhatsApp signifies that your message has left your device and is currently being transmitted through WhatsApp's servers to the intended recipient.
