Youre in an old version of your Android, and 3g has discontinued. The myth has a lore: The phone number calls you while you don't have a sim card inserted. And then they'll appear as @#$ (caller encoding error) in their names. This happens if you're on an old version of your system while you (still) have 3G. It's a caller trying to communicate with your 3G, and sometimes this is cyberphobia.
