When someone you've blocked tries to text you, you will not receive text messages from them. The blocked person also does not receive any notification that they're blocked.
If you've been blocked, the recipient will not receive a notification and won't be able to respond. If you don't receive a returned call or text message within a few days, there's a good chance you may be blocked.
Blocking Texts on Android
Navigate to the Messages app. Choose the text from the number you want to block. From the drop-down menu, select “Details.” From the following screen, tap the option for blocking the number.
If you send a message as a regular SMS in the green text bubble and you do not get a “Delivered” notification but instead get a notification similar to “Message not Delivered” or no message at all, that means you were probably blocked.
Blocked text messages disappear
When someone that you've blocked texts you, their texts go nowhere. They won't receive any notification that they're blocked, and their messages will still look like they've been sent. But you won't receive any of them, and you can't respond.
If an Android user has blocked you, Lavelle says, “your text messages will go through as usual; they just won't be delivered to the Android user.” It's the same as an iPhone, but without the “delivered” notification (or lack thereof) to clue you in.
Blocking Someone on Android Messages and Apple iMessage
When you block a contact over Android or iPhone, they will still be able to send you text messages. These messages will not show up on your phone but the sender will see the messages as sent. They won't know that they've been blocked.
If you call a phone and hear the normal number of rings before getting sent to voicemail, then it's a normal call. If you're blocked, you would only hear a single ring before being diverted to voicemail.
When you block a phone number or contact, they can still leave a voicemail, but you won't get a notification. Messages that are sent or received won't be delivered. Also, the contact won't get a notification that the call or message was blocked.
Silencing a contact is like a “soft or partial” block. You won't get notifications when silenced contacts send you messages. The messages won't even appear in your iPhone's inbox, but you can view them whenever you want to.
Their messages will still look like they're sending, without any notification that they're not being received. If they try to call you, though, it will always go straight to voicemail, which may mean they can eventually figure out that you've blocked them.
A green bubble could also indicate that someone blocked you, especially when the bubbles have always been blue. When blocking occurs, iMessage sends your text, but the recipient never receives it. Your old messages remain blue, but the latest texts you send after they've blocked you turn green.
Blocked messages will not come through when unblocked.
While someone is blocked, any sent text messages will be blocked by Messages. You won't be able to retrieve them.
Activating Airplane Mode on iPhone is another way to block incoming calls and SMS texts without using iOS's blocked contacts list. It works by shutting down your iPhone's cellular capabilities. Anyone attempting to reach you will receive an unreachable phone response.
once you have blocked someone you can not call or text them and you can not receive any messages or calls from them either. you will have to unblock them to contact them. once you have blocked someone you can not call or text them and you can not receive any messages or calls from them either.
When you send them an SMS and you get the "Delivered" notification underneath it, you weren't blocked. If you get a notification like "Message Not Delivered" or you get no notification at all, that's a sign of a potential block.
This action does not “block” emails, as in refusing to receive new conversations in this thread; it simply sends the future emails it receives in the thread to the “Deleted Items” folder. You can easily open the Deleted Items folder and view the ignored conversations, if needed.
