Don't believe messages like the one you got-the person is most likely running a Nigerian 419 scam, where he lies to you about winning so you will send him your money and details in order to claim your ?prize?. In reality there is no prize, and he will keep your money, block your calls and steal your identity. The message can have a virus in it that copies your sim card, phonebook, photos and bank information, so delete it, do not reply even to text Stop.
For more information about the scam and how to protect yourself, read my posts on whocallsme under 447773744001 pages 1-4.
