I've recently moved to the US, and I wanted to get myself a Spitify account (hah). I had to wait for SSN for a few weeks, so no bank account yet - my only option was a prepaid Visa card. Bought one at QFC, used it with PayPal (a fresh account, as my old one is tied to another country) - and found it blocked the next day. PayPal had asked for an ID and address confirmation.
I had my passport, but no utility bill (I was still using Airbnb, just looking for a long-term place to live). Asked support if there's anything I can do - and got nothing useful besides "we need a driver license or utility bill", even though I specifically asked what else could I provide if I don't have either of those (I had a mailing address from a forwarding company). Account was unusable, all I could do with it was logging in :)
Then I've rented apartments and tried to send them a lease contract (with my full name and address) and it was rejected. Not an utility bill, right. Asked support about it, got no reply at all.
Waited for a month, got electricity bill, and only then my account was unlocked.
So, anything unusual - and even if you don't receive any money, you account could be blocked.
...but the core problem is this argument is in reverse anyway: if I get banned from Bank of America somehow I don't lose access to the concept of a card that lets me pay for my Verizon account, and in the worst case scenario I can send them a check. I have had serious issues with Verizon paying for my account before (they both claimed I was behind on payments but would not accept money without a PIN number, which I could only get by verifying my address using a post card that would take forever), but it wasn't a catch-22 scenario where I lose my phone number as there is somehow literally no way to pay for their service again.
