Carrier authentication is not huge. The vast majority of communications services today are secure without a SIM, even ones that are tied to your number. Ever notice that iMessage keeps working without a SIM? The SIM card is mostly a relic that is useful to the carrier oligopoly because it increases network switching friction.
- kevinchen 9y agoIf someone is able to authenticate as your phone number, they can set up iMessage and receive a copy of your future messages.
- sgrove 9y agoWouldn't they need to at least need to log in with your iCloud credentials?
- foolfoolz 9y agonope iMessage does not require iCloud
- dkonofalski 9y agoThis is wrong. iMessage uses your Apple ID and is definitely iCloud based. That's how it can tell the state of messages from device to device.
- foolfoolz 9y agoyou wouldn't be able to authenticate on the data network without a sim. unless you exclusively use wifi the carrier network is still a huge part of everyone daily phone use
