As we all know the existing GSM network is not secure anymore, GSM attackers showed how they could listen in others' calls. This article gives us more information about how the law enforcement and attacker intercept our phone calls.

How can your calls be intercepted, possibly

Back in the olden days, a simple scanner could tune into any cell phone call. Even an older TV which went up to channel 83 (UHF) and had a manual tuning knob (or button), as most TVs from the early '80s did, could be used, often just with rabbit ears for the antenna. However, you could hear only one side of the conversation, as the other was on a different frequency (full-duplex).

No, you are not the only one, but it's beside the point. Actually, it's a girlish GSM hacker showing us how he can hack into the GSM network and that's the point.

That's interesting, but I am too young to see that kind of stuff. However in the early 1990s, I did hear strange voices when I call somebody using landline. In a few seconds I was connected to the one I am calling. Never figure out who's speaking, maybe the operator?

You could do it until at least the late 1990's (and probably past then) around here. Scanners (in the U.S.) were required to have "gaps" in their coverage in the early 1990's as the result of an embarrassing interception of a congressman's conversation, but they were still technically capable of receiving cell phone signals and a defeat of the manufacturer-imposed "gaps" was quite easy for the electronically-inclined. And there was an abundant supply of older scanners and TV sets from the 1980's, which covered certain channels that were auctioned off to mobile phone companies.

Switching from analog to digital ended this, but even I remember my cell phone sometimes being on analog networks as late as 2005.

I would like to see them myself, we here hardly see any TV set even from the 1990's. I would get one from the 1980's if someday I travel to the US.
