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.
If you call and it goes straight to voicemail that means you are not blocked and the person is already on a call or their phone is off. According to Tom'sGuide.com, if you decide to leave a voicemail with a blocked number it will not go to their inbox, but instead to another inbox for blocked numbers.
Because blocking the caller on the phone just automatically rejects the call, in which case it goes to your carrier's voicemail system. The only way to prevent that would be to block them at the carrier level.
Count the rings before voicemail
It's a normal call when you call a person and hear the usual number of rings before getting voicemail. But if the person has blocked you, here's the big indicator. You only hear a single ring before being diverted to voicemail.
For Android, go to Settings > Call Settings > Additional Settings > Caller ID. Then, select Hide Number. Your calls will remain anonymous and you can bypass the blocked list.
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.
Their device will continue ringing (on their end) until the blocked person eventually hangs up the call. You won't be notified in any way and (unlike with a standard voice call) the blocked person will not have an option to leave a voicemail.
Call your contact back with a masked number.
If the call goes through like usual--e.g., five or more rings--then your contact has blocked your number. If the call still stops after a ring or less and diverts to voicemail, your contact's phone is dead.
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. This can be a lifesaver in needing those blocked messages for various reasons after the fact.
If someone has blocked you, you will only see one grey tick, indicating that the message was sent but not delivered.
“The simplest way to tell if you have been blocked by an Android user is to call,” Lavelle says. Just like with an iPhone, listen for it to be diverted to voicemail or play you a pre-recorded message.
Call blocking or call forwarding is turned on. Both reasons may cause any or all phone calls to be sent to voicemail. Simply visit your phone settings to see if your phone lists any blocked numbers or blocks unknown phone numbers or spam calls. Then, you may turn this option off if you like.
Among the handful of things that might automatically send your calls to voicemail is your phone's Do Not Disturb mode, blocked numbers, call forwarding, Bluetooth connections, and your phone's SIM card. Whether you accidentally activated any of these phone features or forgot you turned them on, don't fret.
Send them an iMessage
A red flag that you've been blocked is when you don't see the delivery status or the read receipt at all. The message you just sent will still be in a blue bubble, but it will have no delivery status below it – not even a "Not Delivered."
If you're blocked, you would only hear a single ring before being diverted to voicemail. An unusual ring pattern doesn't necessarily mean your number is blocked. It may just mean the person is talking to someone else at the same time you're calling, has the phone off or sent the call directly to voicemail.
The psychology of blocking someone can evoke indignation and a sense of rejection, reminiscent of the social dynamics of high school. Blocking someone sends a clear message, but it's a cowardly move to run away and hide behind our devices.
Usually, when a person blocks you, they don't want to speak or interact with you. While this is the typical implication of getting blocked, he might have used the block button to get your attention. Sometimes, getting suddenly blocked could be a desperate move for him.
If you're blocked by someone, your calls will go straight to voicemail, and your voicemail messages will head to the 'blocked' section immediately. The other person won't receive your calls, won't be notified you called, and won't see a badge for your voicemail.
Block Listing works by blocking your phone's unique identifier (IMEI number). When a phone is block listed because it has been lost or stolen, it cannot make or receive calls or use data.
You can also use *82 to unblock your number in case your call gets rejected temporarily. Some providers and users will automatically block private numbers, so using this code will help you bypass this filter. Blocking your number can go a long way in stopping annoying robocalls.
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.
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. When you block an email address from Mail, it goes to the trash folder.
