Of course, you’d like to know whether someone has blocked you on Signal. Unfortunately, Signal does not tell you who has blocked you.
Calls you make will appear to go through normally, and you will not receive any special notification when you send a message to someone who has blocked you. However, the person who has blocked you will never receive your messages and will also not see any incoming or missed calls from you.
One possible indication that you have been blocked by someone is that all your messages to that person only show one check mark. Messages you send to someone who has blocked you are not delivered to them. However, note that there are many other reasons why a message may not be delivered and therefore only shows one check mark. One check mark does not necessarily mean you have been blocked. In most cases, it is due to a connection issue on the recipient’s side or maybe the person has uninstalled the Signal app.
Another indication could be that you no longer get any updates about changes to someone’s profile, such as their profile picture or name.
