Says Thank you shopping at bestbuy, you won $1000 bestbuy card please got to http://winner.bestbuy.com.cards4unow.info/ It was a text message. how do they get our numbers?
They're probably robo-dialing. There are only 10 digits in phone numbers and a computer can easily call/text every one of them. This is a version of the advance-fee-for-something scam where something is a grant, grant paperwork, business plan, loan, scammed-money refund, lottery winnings, interest rate reduction, tax reduction, gift card, refund, doggie, cruise, vacation, free gas, etc., and the advance-fee is for tax, shipping, registration, insurance, secure handling, processing, etc. They may send you a fake check, may want your credit/debit card or bank account number, or tell you to wire cash via Western Union, Moneygram, etc. They can put recurrent difficult-to-cancel monthly charges or a 1-time charge on your card or bank account, and sell account info to other criminals and you'll have to replace accounts altogether. Wired-cash is irretrievable - once it's picked up at the other end, it's untraceable and gone. If they want you to call them up for instructions, they may tell you not to discuss the wire with Western Union desk clerks but the real reason is WU clerks are familiar with these scams and will warn you not to wire the money. If you give them the WU Money Transfer Control Number (MTCN) for the wire, they can pick up the money from anywhere in the world.
