Sounds like a classic case of ‘did they block me or is their phone being dramatic again’. Okay, first off, when you call, does it ring once and then go straight to voicemail? That might mean you’re blocked—OR it could just be their phone’s off, because Apple loves keeping us guessing. If their phone is dead or in airplane mode, you’d get the same single ring-to-voicemail thing. Pretty unhelpful, I know.
Now, send a text. If their iMessage bubble stays blue and says ‘Delivered’ under your message, congrats! You’re not blocked. If it’s green? Well, that could mean their phone died, they’re out of service, or yes, you’re blocked. Thanks, iMessage, for the ambiguity. BUT if all your texts stop going through suddenly, big yikes—you’re probably blocked.
If you’re really desperate to Sherlock this, try calling from a different number. If it magically goes through, yeah, you’ve probably been ghosted (sorry, it sucks). Or just wait a while. If they’re still MIA, their phone might just be having a rest day. Hope for the best, prepare for the worst, right?
