Hi! My GS299 expired already so i want to register again. But 8888 replied "Sorry, but you're registered to another mobile surfing promo that can't be used together with GoSurf. You can wait for your current subscription to expire, or you can stop it and register to GoSurf. Stopping a promo will forfeit your unused data. For other mobile data promos, dial *143# or text SURF to 8888 for free."
