Who called from 6506189523

This is definitely from the Viber ap. You have to type your mobile number into Viber to get an activation code. I guess people are typing their number in wrong and the calls go elsewhere.

Zdravím všechny! Nereagujte na volání z těchto čísel "+1(650)618-9523" a "+0000000000" !!! Mohli byste se dostat do problémů.
