Excuse me? Do you have any idea how telecommunication companies work?

@pleegwat If it's a voice call and you're near the device you can just to the person talking

@lolwhat not to mention having two lines with the exact same phone number ACTUALLY HAPPENS.
That happened to a coworker when someone social engineered T-Mobile into stealing his phone number. Ultimately, he had to get a new phone number. (To say nothing of all the financial accounts)

@lolwhat And I don't think mobile voice/SMS is eve encrypted so you can eavesdrop it if you're near the device?
Generally speaking, yep. Encryption would cost money and impose a performance hit. At least digital mobile is a bit more secure than analog, where anyone with a radio tuned to the right channel could hear a mobile conversation entirely in the clear.

I remember as a kid accidentally listening in on some cordless phone conversations from quite a ways away using a cheap set of walkie-talkies.

Weird, I remember my Mobile Networks teacher telling us all mobile phones used a fixed shared-secret encryption between the SIM card and the operator (which would be used for pretty much all communications involving the operator, which means NOT bluetooth or wi-fi).
However, by today's standards that encryption might be WEP-grade...

the SIM card
The GSM standard was the first to use SIM cards. Plenty of standards prior to GSM - including AMPS and other analog standards - most assuredly did not.
And I went overboard with saying that there's no encryption. I should have said that the encryption isn't very good (yeah, WEP-grade would be a good way to put it), although I suppose it will get better once VoLTE becomes more widespread:
