To smart postpaid users, @smartcares: if you receive the following message from an unknown number (not access code), it is hoax. Message: “SMART: You’re the one selected postpaid plan given 35% discount billing, to get your 35% discount billing, just forward 15-digit secret code to 8080. You will receive 15-digit secret code on next message. Please wait!”
