If someone who usually replies to your messages suddenly goes quiet, you may wonder whether they have blocked you. Maybe your messages no longer seem to reach them, your calls do not connect, or their profile details have changed.
Most messaging apps don’t explicitly tell you when someone blocks you. This guide explains how to know if someone blocked you, from changes in message delivery to call behavior and profile visibility.
5 Signs Someone May Have Blocked You
1. Your Messages Stay Undelivered
Your message status may change if a message isn't delivered. On imo, a single blue check mark means a message has been sent but not delivered. If your messages consistently show this status, a block is one possible explanation.
A single check mark can also mean that the other person's phone is offline, their internet connection is unstable, or their account is no longer active.

2. Your Calls Don't Go Through
Voice or video calls may stop connecting as they normally do. Your calls might fail to connect or end before the other person answers. Repeated call failures may be more significant if calls to other contacts still work normally.
3. You Notice Changes in Their Profile
Their profile photo may disappear, or details you could previously see may no longer be visible. On some messaging apps, blocking can limit access to profile information and updates.
Privacy settings can produce similar changes. Someone may limit who can see their profile photo or remove it altogether.
4. You Can No Longer See Their Activity
A person's last-seen time, online status, or Stories may disappear from your view. On messaging apps, blocking can limit access to this activity and content.
5. Several Signs Appear at the Same Time
Undelivered messages, repeated call failures, and missing profile information occurring around the same time may point to a block more than any one of these signs alone. Even when several changes happen together, they cannot confirm a block. An inactive account or a prolonged connection problem may affect more than one feature at once.
For privacy reasons, imo cannot confirm whether someone has blocked you, identify who has blocked you, or remove you from another user's block list.
Other Reasons You May Notice These Changes
Similar changes can occur for reasons unrelated to blocking, including connection problems, privacy settings, and account changes.
Internet or connection problems. If the other person has poor mobile coverage, an unstable Wi-Fi connection, or a device that is offline, messages and calls may not reach them normally. This can last longer if they are travelling or unable to access a reliable connection.
Privacy settings. People can often choose who sees their profile photo, online status, last-seen time, and other account details. If some information disappears while other features continue to work normally, a change in privacy settings may explain it.
An inactive, deleted, or changed account. Someone may stop using an app, switch to a new account, or delete their existing one. This can affect whether their profile appears and whether messages or calls reach them.
Temporary app or device issues. Outdated software, service disruptions, or problems with a person's phone can interfere with messaging and calls. If similar problems occur with several contacts, the issue may be with your own connection, device, or app rather than with one particular person.
What to Do If You Think Someone Blocked You
Give it some time. If the change is recent, wait a while before deciding what it means. The person may be travelling, dealing with connection problems, or taking a break from the app. Repeatedly checking their profile or sending test messages won't give you a reliable answer.
Avoid trying to get around a possible block. Creating another account, repeatedly calling, or asking others to check the person's activity can cross privacy boundaries. If someone has chosen to limit contact, respect that decision rather than looking for ways to bypass it.
Consider whether another message is appropriate. If you have a genuine reason to contact the person and already communicate through another channel, one brief, respectful message may be reasonable. Give them the option not to respond. If they have clearly asked you not to contact them, do not reach out through another account or platform.
You may never know exactly why someone stopped responding. Instead of trying to interpret every change in their online activity, focus on what you can control and decide how you want to move forward.
If you're considering blocking someone yourself, learn what happens when you block someone, including how it affects your chats and calls.
