@Legit Welcome to PM. Make sure that you used the correct code and the person who gave it to you received SMS about code's usage and 1$ reward. In that case, you will get 10$ within 3 days usually.
Your friend who referred you may have already received a text message saying they had successfully referred a friend. That happens almost immediately unless the activation was into the evening in which case the text message arrives the next day.
Within 72 hours of activating your $10 credit will be applied to your account provided you entered the referral code on the activation page when activating your sim card.
