is there anyway to view these blocked messages after they have been blocked?

Is it possible to allow known people to send me SMS and block only unknown senders? I tried it and all the incoming messages were blocked. Another problem is that it wasn’t possible to read the blocked messages.

Well you can do that and for this you need to select the option except messages from contact. This means that if any person who is not on your contact list send u a message it will be blocked, but if they are present in your contact list you should receive them without any issues……
