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.
Android users may determine if someone has blocked their number by checking notifications. If the “sent” icon changes to “delivered,” the receiver is likely not blocked you. On the other hand, if it stays on “sent,” there's a good chance they have blocked your number.
“The last message that you know was received and responded to…should have a 'delivered' status,” Lavelle explains. If, under the messages you've sent after that, you don't see that “delivered” notification, that could mean that person has blocked you.
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 you have been blocked by someone on Android, then it is likely that you would want to text them. Unfortunately, since you have been blocked, there is no way to get your texts delivered.
Android phones move all blocked messages into a folder on the phone called “Spam and Blocked.” That means that the phone is still collecting messages from the blocked people; they just aren't notifying you.
1. To know if someone blocked you on iPhone, call them to see if you go straight to voicemail. Calling someone is the best way to know if someone blocked your number on iPhone! If you call the other person and the call goes straight to voicemail (with barely even one ring), you've likely been blocked.
When you call a number that has blocked yours, you may hear one or half a ring or no rings at all and then the call will go to voicemail. If it goes straight to voicemail, their phone may also be off or out of range, or they may have temporarily turned on Do Not Disturb mode to work, drive, or sleep.
If the call ends after one ring (or, in some cases, half of a ring) and you are diverted to voicemail, you are either blocked or your contact's phone is dead. If the phone immediately hangs up or beeps rapidly, then either the line is busy or the contact blocked you through their carrier.
Dial *67. This code will block your number so that your call shows up as an "Unknown" or "Private" number. Enter the code before the number that you're dialing, like so: *67-408-221-XXXX. This may work on cell phones and home phones, but it won't necessarily work on businesses.
Another way to know if someone blocked you on iMessage is to check the bubble color. If you see green bubbles, this means that your text messages are being sent through SMS, and they might have blocked you on iMessage.
If the chat bubble is green, that could indicate someone has blocked you, especially if your chats with this person used to be blue. However, this is only true if both of you use iMessage on iPhones. If the other person switched to an Android phone, their bubble may have turned green (plus, they may have a new number).
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.
One way to test this situation is to leave a voicemail and wait. 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.
If your iPhone messages are green, it means they're being sent as SMS texts rather than iMessages. You'll always see green when texting Android users, or when you're not connected to the internet.
If you have confirmation that someone has blocked your contact on their phone, there's no way to unblock yourself remotely using any of your devices. To unblock your number, you need to either have physical access to the person's phone or talk the situation through with them and have them reverse the action.
One method you can use on any type of phone is by calling the person you suspect has blocked you. While typically you can expect to hear anywhere from three to 12 rings when you call someone before going to voicemail, a blocked number will only ring once and then go straight to voicemail, according to Tom'sGuide.com.
Once your carrier sets you up with a private number, you can still use *82 if you run into call rejection. This step temporarily unblocks your number on a per-call basis. While you're on the phone, call your internet provider, too.
This Vertical Service Code, *82, enables calling line identification regardless of subscriber preference, dialed to unblock withheld numbers (private callers) in the U.S. on a per-call basis.
When you're blocked on iMessage, Apple's messaging service prevents your instant messages from getting delivered to the person you're trying to reach. If you have text message fallback enabled, your device will resort to sending the message as a text, meaning the bubble will turn green after someone blocks you.
