I am trying to switch my post paid plan to pre-paid and for now , keep the same phone. I've gotten as far as verifying my IMEI number and also ordering a new sim. But when I select a plan and hit enter, I get this message: Invalid Address. Please verify and update your address on the account. My address, both billing and service appear accurate. The only issue I can see is that the zipcode is 5 characters and not 9. But it doesn't allow me to update it to nine. So I don't know what this error message means and what account they are referring to.
