So I have 3 lines on my phone plan with Cingular/ATT - 2 lines are on a family plan, and 1 is freestanding - the question that I have is - is it possible for me to block the other phones from getting the balance on the account - or for the two "accounts" to be billed separately, and the balances displayed differently on the phones? I.E - freestanding line receives only the balance they need to pay, and the 2 family plan ones get one that doesn't include the freestanding one? Any help is appreciated!
