In the US and EU, even a blocked number can reach 911 or 112. But more relevantly, can bypass blocks. If you call from a landline or a different carrier, sometimes the "block list" doesn't sync perfectly. But this is a glitch, not a feature. how to unblock a phone call

When you block a number on an iPhone or Android, you aren’t deleting them from the universe. You are simply telling your carrier: “When this number pings the tower, do not forward the payload to my device.” However, there is one network layer untouched by
The blocked caller usually hears one ring (the handshake with the tower) followed by a generic "Subscriber cannot be reached" or straight to voicemail. Crucially, the block is .

This blocks your caller ID. On a landline or older mobile network, this was the universal skeleton key. The receiver saw "Unknown Caller" and, if curious, picked up. But this is a glitch, not a feature
