@spud18 yes a referral code meaning a friend or family member referred you to Public Mobile. When you activate a sim card while signing up there is a spot to enter the code. You'll get $10 credit to your account for it that can be used on 2nd payment for your plan.
It sounds like you don't have one so if you look at top right of your page the envelope. That is your private message inbox. I sent you one if you want to use.
If you have any further questions we are here to help.
Once you have a sim card go to link below to activate.
