Who called from 4073762563

SCAM: "you've been chosen to win a $1000 Walmart gift cart! But only the 1st 1000 users that enter code 7777 at http://1000dollars.mobi will receive it!"

Both my BF and I received this message my question is where are they getting our numbers to send such

I received an unsolicited text msg from this telemarketer telling me I had been chosen to win a $1000 Walmart gift certificate. I have filed a complaint with the FCC. Please, I hope anyone else does the same.

By the way, Google "$1000 walmart gift card scam", you'll see that this is a scam.
