Q&A for How to Know if Someone Blocked You on Apple Messages

If the messages are not delivered, then either your ex-boyfriend has blocked you or the messages couldn't reach his phone.

If you call the number, hear only one ring, and are then sent to voicemail, there is no cause for concern. This doesn’t always mean you’re blocked; as it could just simply mean that the person you’re calling’s phone may be dead.

This can happen for multiple reasons. 1. Make sure you have internet access. 2. She may have blocked you given you had a fight. 3. Your service may be down. Try again when things have cooled down and go to her in person to apologize.

If they blocked you, there is now no way for you contact them via messages.

If the voicemail says the contact is unavailable, the receiving phone might be powered off, out of signal range, or the calling number may be blocked.

If your message switched from "SMS Text" to "iMessage," it likely means your girlfriend unblocked you. When blocked, messages are sent as SMS, but once unblocked, iMessage restores if both devices are connected. It could also happen if iMessage was temporarily off or there were connection issues. If it’s important, consider asking her directly.
