Don't take the title too literally.
Ok, I'm a student and when I applied for an account with NatWest, they gave me solo cards. These things are quite frustrating, I can't buy any mobile phone contract deals with these. How do I get anything besides a solo? Do I just go to a Natwest branch and ask for an upgrade? Would I have to pay for the upgrade?
PS. I'm a British citizen, if that matters in anyway.
