Somebody tried a scam on me today. My cellphone rang and stopped after one ring, before I could respond. I looked at the "missed call" message and fortunately I checked the telephone number of the caller before I responded. It was (camouflaged by adding the country code of Germany) a 0190 number. In Germany these numbers are usually rented out to businesees, who charge for services through the telephone bill. Theoretically one call to such a number can cost you up to $1000,- per call, no matter how long. The person deliberately tried to make me call back and would have then charged me a huge amount, and I would have had the onus in court to prove that I was scammed.
Do there exist similar scams in other countries?
