While your phone is blocked, you won’t receive any calls or messages from the blocked number. So, anything that person might’ve sent you while their number was blocked, there’s no way of seeing those messages.
Now, if you decide to unblock a number, you’ll start to receive calls and messages from that moment forward. Fortunately for iPhone users, the way to unblock contacts is just as easy as blocking them.
