Got a call to my cell phone.  My name is also Raul. ..weird.

I answered the phone and sat silently, waiting for someone to talk and they just hung up..

This is a secret government agency spying on you. BwahahahA

Just another phone scam call, you answer and they hang up.   It's like a computer just testing the water to see if it is a valid number so someone in the future can call.  IDK???

Tried to block this number from my T-Mobile Galaxy phone using my Family Allowances service on the T-Mobile website. I was not able to add the number to the "do not allow" list. Called T-Mobile, the rep was unable to add it either. After researching I was told that this is a spoof# which hides the real number. The solution for me was to add the number as a contact on my phone ( I call it Spoof Number)  then go into settings and add it to the reject list on the phone. Hope this helps.
