Got a text from this number saying, "You have been selected to receive a FREE $50 Walmart Gift Voucher Call 1-877-552-3586 to redeem. TXT STOP TO STOP"

Really???
What a bunch of B.S.

I've seen these types of texts before, claiming I won a free gift voucher to Target, and one to Applebee's, so I know they are just phishing for phone numbers to clone and/or spam with more texts.

Do not respond in anyway. Just delete them and forget it.

Geez. Got another one half an hour later of the same thing

received text message that I just won a FREE  $50.00 gift voucher from Home Depot and
to call 877 552 3585 to redeem. TXT STOP TO STOP
