Nightmare with Student Bank Account. URGENT ADVICE NEEDED Watch
Just be aware that you are unlikely to get a low rates card until you have a history of reliably paying back debt. Its chicken and egg, but if you default paying back a card and get a bad credit score then you wont be able to get a mortgage, bank account, loans at good rates, etc.
its better to live within you means, or you parents, if you get county court judgements for not repaying debt on cards, loans etc then it takes a long time to recover.
My advice, don't get a credit card, without substantial income they are a bad idea. The friend you have that got them their credit scores were probably base on the address they gave, parental credit scores etc.
