If you block a contact on your phone, will they still be able to message you on WhatsApp - in detail?
If you block a contact on your phone, it does not automatically prevent them from messaging you on WhatsApp. The blocking feature on your phone primarily restricts calls and messages through the standard SMS and phone call services provided by your mobile carrier. It does not extend to third-party messaging applications like WhatsApp, which operate independently of your phone's native communication systems.
WhatsApp uses an internet connection to send and receive messages, photos, videos, and voice or video calls. The blocking feature on your phone does not interfere with this functionality. Therefore, if someone has your contact number saved in their WhatsApp contacts, they can still attempt to message you through the app.
However, it is important to note that while they may be able to send messages, those messages will not be delivered or seen by you if you have blocked them on WhatsApp itself. WhatsApp has its own blocking feature that works independently of your phone's settings. When you block a contact on WhatsApp, their messages are not delivered to your device, and they cannot see your last seen status, profile photo, about information, or any changes made to these.
In summary, blocking a contact on your phone does not affect their ability to message you on WhatsApp. To prevent them from sending messages via WhatsApp, you must block them within the WhatsApp application itself.
