What does one check mark on WhatsApp mean - in detail?
A single check mark on WhatsApp indicates that your message has been successfully sent from your device to the WhatsApp server, but it has not yet reached the recipient's phone. This initial check mark is visible only to the sender and serves as a confirmation that the message left your phone and is currently in transit. However, it does not provide any information about whether the recipient has seen or read the message. For complete delivery confirmation, you would need to see two check marks, indicating that the message was delivered to the recipient's device.
