Prism says my phone number is already registered!
The most likely cause is that you may have signed up for Prism in the past, you have signed out and then selected to create a new account, or you got a new device and reinstalled Prism.
The best thing to do would be to sign out of this account and then sign back in with your phone number, the one already associated to your previous Prism account.
If you select the Account tab, you will see the option to Sign out of Prism at the bottom of the menu. Next, choose "Already have an account?" located toward the bottom of the screen and you will be prompted to sign back in. All you need is the phone number and password associated to the account you wish you log into, all of your billers and accounts will sync back over. If you still have issues, let us know through Support!
