Will SMS messages get through in WhatsApp if the contact is blocked - briefly?
If a contact is blocked on WhatsApp, standard SMS messages will not be delivered to that contact.
Will SMS messages get through in WhatsApp if the contact is blocked - in detail?
If a contact has been blocked on WhatsApp, traditional SMS messages will not be affected and will still get through. This is because WhatsApp and standard SMS operate on different protocols and use distinct methods of communication.
WhatsApp uses Internet-based messaging protocols, which means it relies on an active data connection to send and receive messages. When a contact is blocked on WhatsApp, the user cannot see your status updates or changes, and you will not be able to communicate with them via WhatsApp's chat feature. However, this block does not extend to standard SMS text messaging.
Standard SMS, on the other hand, operates through cellular networks and uses a different set of protocols. When you send an SMS message, it is routed through your mobile carrier's network to the recipient's mobile device, bypassing WhatsApp entirely. As such, blocking a contact on WhatsApp does not prevent them from receiving your SMS messages.
It is important to note that while blocked contacts cannot see your WhatsApp status or changes in your profile picture or display name, they can still call you using their phone's standard dialer. This call will come through as a regular voice call and will not be affected by the WhatsApp block. However, if you wish to prevent calls from a blocked contact, you may need to use additional features provided by your mobile device or carrier.
In summary, blocking a contact on WhatsApp does not interfere with standard SMS messaging. Traditional SMS messages will still get through to the blocked contact via their cellular network provider.
