For those here in the Philippines, text RED [amount] to 4493 (for Smart) or 2899 (for Globe). Any amount will help! If you're on a line like me, it will show up on your bill, I'm sure. If you're on prepaid, they'll deduct it from your load methinks. For those who are in other countries, please check with your local Red Cross.
