Download the Pi Network app and while entering in your information, you will see the box where it asks for your referral/invitation code. No expiration date, but you won’t be able to mine Pi from your phone for too much longer so start now while you can still mine from your phone!
Use my code when you first signup. Make sure you don’t forget to do it. If you forget during the initial signup, you’ll have exactly 7 days to use my referral code or else you will miss out completely.
