Not demagnetized but maybe just broken? Can happen and they should just replace the sim.

Yes, nothing to do with magnetism, this 
Maybe it was just this shop-rep using some slang expression for "dead" or "broken"

Read about this on XDA, and almost never was the fault of the phone (my phone never overheated, never drained battery more then normal or stuff like that), so the questions still remain... WHY? WHY DOES THIS HAPPEN?!

Now here's his variant of the story: The SIM is like a fuse for the antenna, so if there are some frequency fluctuations the SIM card is the first one that gets fried just to protect the GSM Driver (chips or whatever). He told me that once a customer came with a FRIED (but the good kind of frying, that the SIM was physically burnt, with visible marks of burning) SIM card, they replaced the SIM and the phone worked beautifully for 2 more years flawlessly until the customer came to get a new phone.
Now still the questions remain, why this RANDOM breakdowns of the cards?

Take simcards, for example. The things are produced by the millions, and they are done CHEAP. The mfg process is tuned so that acceptable amount of cards pass the tests, and also the life expectancy of the cards is not that long, thy are designed to last for a couple of years. Once in a while there's going to be a manufacturing defect that hits somebody and now it was just your bad luck to get one.

But now, with your explanation I chilled down and started thinking that it's not a hardware problem, it's excluded (you know tests might be wrong, so I think it's excluded) to have a hardware problem...

Also, I want to think this is just my superstition, but this happened right after I got a new very powerful router (a 2.4Ghz N router with 3 X 9dbi antenna) and this occurred right after I fired up that monster, but I want to think this is is just my imagination and that router did not burst an EMP shockwave (played and made some EMP's - small ones - in my life) when it was powered up...

For EMP you need a lot more energy.

....speaking of 'demagnetizing', hotel / parking lot access cards can get demagnetized, by placing them in very close proximity to your cell.
(of course the magnetic swipe type only.)

Of course, if some spike hits the antenna or powersupply (like an EMP), it will fry the SIM. But also the GSM controller and other stuff.
Just take it from me, the electronics in the SIM just died, no need to look for an explanation.

Okay, f**k this s*it, I bought this brand new phone with 2 years warranty and 1 year paid insurance, somebody have to fix it for me. I called Orange Care, they told me to call the HTC Support and so I did. I checked every step they told me, and still nothing, same error (switched the phone on/off, remove - reinsert SIM), so they finally they told me to go to the closest Orange Store (opened today) for advanced diagnosis.
Got there, they installed the diagnosis software, checked it, and checked the logs and the only error was a missing SIM card (fhew, the hardware is okay) but the SIM was "DEMAGNETIZED" (that's how they call it) and they showed me that my phone would read other SIM cards but not that one, that one IS DEAD!
Okay, I got home, found an Orange SIM, chopped it down to the size, and guess what, the SIM was found (not active anymore) but found...! Now I will have to go to the central Orange store tomorrow and have a fight with those guise to recover my number and my minutes/options active on that SIM (it was 2 weeks old!)
My question now, why do SIM cards get "DEMAGNETIZED"?
