If the number is blocked, can I call them on WhatsApp - briefly?
If a number is blocked on your phone, you will not be able to call or text that person using WhatsApp either. This is because WhatsApp uses the same contact list as your phone and respects the block status set there.
If the number is blocked, can I call them on WhatsApp - in detail?
If a phone number has been blocked, it does not necessarily mean that you cannot communicate with the person via WhatsApp. This distinction arises because blocking a number typically applies to traditional voice calls and SMS, which are governed by different protocols and technologies than those used by messaging apps like WhatsApp.
WhatsApp utilizes internet data to facilitate communication, which operates independently of the traditional phone network. When you block a contact on your mobile device, it usually affects only the capabilities tied to that specific network—such as standard voice calls and text messages. However, this restriction does not extend to internet-based services like WhatsApp.
Therefore, if someone has blocked their number from receiving traditional phone calls or SMS, you can still attempt to contact them via WhatsApp. The person will have the option to accept or decline your call on WhatsApp, just as they would with any other contact. This means that even if a number is blocked for standard communication methods, it does not preclude the possibility of reaching out to them through WhatsApp.
However, it's essential to note that the recipient can choose whether or not to answer your call on WhatsApp, and they also have the option to block you specifically within the WhatsApp app itself if they wish to prevent further communication from you. This ability to control who can contact them via WhatsApp provides users with an additional layer of privacy and security.
In summary, while blocking a number may restrict traditional phone calls and SMS, it does not inherently block communication through WhatsApp. You can still attempt to call the person using WhatsApp, but whether they choose to answer is at their discretion.
