Who is this. Im from germany and this number call me everyday. Should i say hello??? Need help!!! Thx

Got a missed called from this number 1-786-565-4821 (Miami, Florida), then another missed called from 1-705-220-4488 (Barrie, Ontario, Canada?, Rogers Communications mobile phone Zip: L4M 7C3) ) then a lewd text message from 1-714-735-7713 (Buena Park, California, LSAGCAJNDS0 phone hobbyists) whatever that is, and I am not even in any of these countries, what the h?

Please tell

Received text and calls with codes. Text mentioned WhatsApp.  Numbers from call were in Japanese. I'm in US. I use What's App and had recommended it to a Japanese friend. Maybe she downloaded a look-a-like version and that is how they got my number.  Likely a way to text $ to an account like one might donate via text message.  I plan to block #.  

I receive numerous calls from +1 786-565-4821 to my temporary overseas number which is associated with a WhatsApp account. I believe it has something to do with WhatsApp authentication or attempts at re-authorization for continued NSA surveillance.
