Ordinal refers to a number indicating the position in a series: 1, 2 and 20 are cardinal numbers, 1st, 2nd and 20th are all ordinals/ordinal numbers.

Hello,

why do you use "as" and not "because" ?

I think that is better : "I am really not interested in mobile phones because I prefer ordinary phones"
