Why do you care about an Uber account? Can't you just create a new account and start over? The accounts I care about are the ones where I've got important files or data stored in them.
In USA, Uber accounts are locked to phone numbers. You can't just create a new account. OP is fucked.
Ah - interesting. I just created a new Uber account here in NZ and during the sign-up process I get this: "Enter your mobile number (Optional)". No need to enter a mobile number.
Must you have a singular phone number in USA ? I don't see the problem.
