i got call from this number, at 1.09am today, i think its a goverment number, they tring track us, do you guys know about ..L3..?, and time by time our phones are listened by agencies, maybe all the times, computers filters our speech, for some illegal words, dangerous words, after your calls will be monitored by agencies for some period...and its possible to activate our cell phones microphone via network also its possible to track our location and monitor our everyday life.
so if somebody makes strange call to you please don't ruin family trust, just be aware of everything
