Hilton HHonors members can get 1,000 points for registering your text-enabled mobile phone number and a Visa card by June 30, 2012. You’ll then receive up to two offers per week via text.

Plus, you can earn 4,000 more bonus points after spending $100 with your enrolled card at a U.S. hotel or resort within the Hilton worldwide portfolio.

You can enroll up to three eligible Visa cards–not all cards are eligible, and only those cards that process transactions in the U.S. are eligible. You can opt out at any time. Visit http://www.visa.com/HiltonHHonors to sign up.
