Do you mean it says invalid? Did you try activating and hit the back button or anything?
Did you pass the payment section?
If yes check if your card was charged.
If it was charged put your sim card in your phone it will likely work.
If it does work and you were charged go to link below to create your self serve account.

If you were not charged. System locks sim for 50 minutes. Wait one hour, clear internet cookie/history cache open a fresh browser in incognito mode and try again.
Don't forget a referral code for a $10 sign up bonus. If you used one and were charged and service works the credit will be applied within 72 hours.
