If you suspect that someone has blocked your number on their iPhone and you are not receiving messages from them, there are a few ways to check if this is the case. One way to determine if you have been blocked is to send a text message to the person in question. If your message is not delivered and you do not see any updates to the conversation, this could be a sign that you have been blocked.
Another method is to try calling the person. If your call goes straight to voicemail every time, this could also indicate that you have been blocked. Additionally, you can check for blocked messages on an iPhone by going to the message conversation that you suspect has blocked you. If there is no response from the other party and you see a “Delivered” status without any updates, it is possible that your messages are being blocked.
By utilizing these methods, you may be able to determine if your messages are being blocked on an iPhone. It is always important to respect the boundaries and privacy of others, so if you suspect that someone has blocked you, it may be best to communicate with them through other means or to respect their decision to block you from messaging them.
