If you block someone's phone number on WhatsApp, they will not be able to send you messages or calls. However, blocking does not prevent them from creating a new account and contacting you again.
Can he write to me on WhatsApp if I block his phone number - in detail?
Blocking a phone number on WhatsApp effectively prevents the blocked user from contacting you through the app, regardless of whether the communication is initiated via message or call. When you block someone on WhatsApp, their messages will not be delivered to your device, and they will not receive any delivery receipts indicating that their messages were read. Additionally, calls from the blocked number will not go through, protecting your privacy and preventing unwanted contact.
The blocked user may still send messages or attempt to call you, but they will not receive any confirmation that their communication efforts were successful. The messages they send will remain undelivered on their end, and any calls made will simply ring indefinitely without connecting. This feature ensures that the blocked individual cannot disturb you through WhatsApp, providing a secure environment where you can control who has access to your digital space.
In summary, blocking a phone number on WhatsApp effectively stops the user from contacting you via the app, safeguarding your communication experience and maintaining your privacy.
