If you have an old positive tab (credit) tab balance it breaks self serve in the following of ways.
These are accounts from when tabs did not stop at $0, before BYOD.
They have positive credits in the system.
- Under tab balance, your positive balance is shown as negative and you can "pay" it off presumably doubling the credit. You can still see it is positive by looking at tab history.
- You cannot select any BYOD plans since you have a non zero tab
- Self serve attempts to force you to upgrade your phone and select a tab plan every time you log in.
